Incorrect IPv4 and IPv6 private ranges

An improper link resolution flaw can occur while extracting an archive leading to changing modes, times, access control lists, and flags of a file outside of the archive. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to gain more privileges in a system.

Impact Passing HTML from untrusted sources - even after sanitizing it - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code.

Patches This problem is patched in jQuery 3.5.0.

Workarounds To workaround the issue without upgrading, adding the following to your code:

js jQuery.htmlPrefilter = function( html ) { return html; };

You need to use at least jQuery 1.12/2.2 or newer to be able to apply this workaround.

In the Linux kernel, the following vulnerability has been resolved:

nfsd: don't ignore the return code of svcprocregister()

Currently, nfsdprocstatinit() ignores the return value of svcprocregister(). If the procfile creation fails, then the kernel will WARN when it tries to remove the entry later.

Fix nfsdprocstatinit() to return the same type of pointer as svcprocregister(), and fix up nfsdnetinit() to check that and fail the nfsdnet construction if it occurs.

svcprocregister() can fail if the dentry can't be allocated, or if an identical dentry already exists. The second case is pretty unlikely in the nfsdnet construction codepath, so if this happens, return -ENOMEM.

HTTP/2 Rapid reset attack The HTTP/2 protocol allows clients to indicate to the server that a previous stream should be canceled by sending a RSTSTREAM frame. The protocol does not require the client and server to coordinate the cancellation in any way, the client may do it unilaterally. The client may also assume that the cancellation will take effect immediately when the server receives the RSTSTREAM frame, before any other data from that TCP connection is processed.

Abuse of this feature is called a Rapid Reset attack because it relies on the ability for an endpoint to send a RSTSTREAM frame immediately after sending a request frame, which makes the other endpoint start working and then rapidly resets the request. The request is canceled, but leaves the HTTP/2 connection open.

The HTTP/2 Rapid Reset attack built on this capability is simple: The client opens a large number of streams at once as in the standard HTTP/2 attack, but rather than waiting for a response to each request stream from the server or proxy, the client cancels each request immediately.

The ability to reset streams immediately allows each connection to have an indefinite number of requests in flight. By explicitly canceling the requests, the attacker never exceeds the limit on the number of concurrent open streams. The number of in-flight requests is no longer dependent on the round-trip time (RTT), but only on the available network bandwidth.

In a typical HTTP/2 server implementation, the server will still have to do significant amounts of work for canceled requests, such as allocating new stream data structures, parsing the query and doing header decompression, and mapping the URL to a resource. For reverse proxy implementations, the request may be proxied to the backend server before the RSTSTREAM frame is processed. The client on the other hand paid almost no costs for sending the requests. This creates an exploitable cost asymmetry between the server and the client.

Multiple software artifacts implementing HTTP/2 are affected. This advisory was originally ingested from the swift-nio-http2 repo advisory and their original conent follows.

swift-nio-http2 specific advisory swift-nio-http2 is vulnerable to a denial-of-service vulnerability in which a malicious client can create and then reset a large number of HTTP/2 streams in a short period of time. This causes swift-nio-http2 to commit to a large amount of expensive work which it then throws away, including creating entirely new Channels to serve the traffic. This can easily overwhelm an EventLoop and prevent it from making forward progress.

swift-nio-http2 1.28 contains a remediation for this issue that applies reset counter using a sliding window. This constrains the number of stream resets that may occur in a given window of time. Clients violating this limit will have their connections torn down. This allows clients to continue to cancel streams for legitimate reasons, while constraining malicious actors.

Prior to Apache HTTP Server 2.4.55, a malicious backend can cause the response headers to be truncated early, resulting in some headers being incorporated into the response body. If the later headers have any security purpose, they will not be interpreted by the client.

A flaw was found in the Apache Portable Runtime Utility (APR-util) library. This issue may allow a malicious attacker to cause an out-of-bounds write due to an integer overflow when encoding/decoding a very long string using the base64 family of functions.

A timing based side channel exists in the OpenSSL RSA Decryption implementation which could be sufficient to recover a plaintext across a network in a Bleichenbacher style attack. To achieve a successful decryption an attacker would have to be able to send a very large number of trial messages for decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5, RSA-OEAP and RSASVE.

For example, in a TLS connection, RSA is commonly used by a client to send an encrypted pre-master secret to the server. An attacker that had observed a genuine connection between a client and a server could use this flaw to send trial messages to the server and record the time taken to process them. After a sufficiently large number of messages the attacker could recover the pre-master secret used for the original connection and thus be able to decrypt the application data sent over that connection.

An out-of-bounds memory write flaw in the Linux kernel’s USB Monitor component was found in how a user with access to the /dev/usbmon can trigger it by an incorrect write to the memory of the usbmon. This flaw allows a local user to crash or potentially escalate their privileges on the system.

A flaw in XML parsing could have led to a use-after-free causing a potentially exploitable crash.In official releases of Firefox this vulnerability is mitigated by wasm sandboxing; versions managed by Linux distributions may have other settings.

All versions of package angular are vulnerable to Cross-site Scripting (XSS) due to insecure page caching in the Internet Explorer browser, which allows interpolation of <textarea> elements.

NPM package angular is deprecated. Those who want to receive security updates should use the actively maintained package @angular/core.

Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in modproxyajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to. This issue affects Apache HTTP Server Apache HTTP Server 2.4 version 2.4.54 and prior versions.

In libarchive 3.6.1, the software does not check for an error after calling calloc function that can return with a NULL pointer if the function fails, which leads to a resultant NULL pointer dereference or, in some cases, even arbitrary code execution.

VMware Tools (12.0.0, 11.x.y and 10.x.y) contains a local privilege escalation vulnerability. A malicious actor with local non-administrative access to the Guest OS can escalate privileges as a root user in the virtual machine.

An attacker can make the Node.js HTTP/2 server completely unavailable by sending a small amount of HTTP/2 frames packets with a few HTTP/2 frames inside. It is possible to leave some data in nghttp2 memory after reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is abruptly closed by the client triggering the Http2Session destructor while header frames are still being processed (and stored in memory) causing a race condition.

A flaw was found in the Serialization component of OpenJDK. The invokeWriteObject() method of the ObjectStreamClass method failed to catch InstantiationError exception during object stream deserialization, which could cause an unexpected exception to be raised when processing an untrusted serialized input.

A flaw was found in the Serialization component of OpenJDK. A reference to an uninitialized class descriptor encountered during object stream deserialization could cause an unexpected exception to be raised when processing an untrusted serialized input.

Fixed bug (1-byte array overrun in common path resolve code). (CVE-2023-0568)

Fixed bug GHSA-54hq-v5wp-fqgv (DOS vulnerability when parsing multipart request body). (CVE-2023-0662)

A type confusion vulnerability was found in OpenSSL when OpenSSL X.400 addresses processing inside an X.509 GeneralName. When CRL checking is enabled (for example, the application sets the X509VFLAGCRLCHECK flag), this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call, enabling them to read memory contents or cause a denial of service. In most cases, the attack requires the attacker to provide both the certificate chain and CRL, of which neither needs a valid signature. If the attacker only controls one of these inputs, the other input must already contain an X.400 address as a CRL distribution point, which is uncommon. In this case, this vulnerability is likely only to affect applications that have implemented their own functionality for retrieving CRLs over a network.

A use-after-free vulnerability was found in OpenSSL's BIOnewNDEF function. The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally by OpenSSL to support the SMIME, CMS, and PKCS7 streaming capabilities, but it may also be called directly by end-user applications. The function receives a BIO from the caller, prepends a new BIOfasn1 filter BIO onto the front of it to form a BIO chain, and then returns the new head of the BIO chain to the caller. Under certain conditions. For example, if a CMS recipient public key is invalid, the new filter BIO is freed, and the function returns a NULL result indicating a failure. However, in this case, the BIO chain is not properly cleaned up, and the BIO passed by the caller still retains internal pointers to the previously freed filter BIO. If the caller then calls BIOpop() on the BIO, a use-after-free will occur, possibly resulting in a crash.

Impact Passing HTML containing <option> elements from untrusted sources - even after sanitizing them - to one of jQuery's DOM manipulation methods (i.e. .html(), .append(), and others) may execute untrusted code.

Patches This problem is patched in jQuery 3.5.0.

Workarounds To workaround this issue without upgrading, use DOMPurify with its SAFEFORJQUERY option to sanitize the HTML string before passing it to a jQuery method.

A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before 9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

An unspecified vulnerability in Java SE related to the Libraries component could allow an unauthenticated attacker to cause no confidentiality impact, low integrity impact, and no availability impact.

A CRLF injection flaw was discovered in python in the way URLs are handled when doing an HTTP/HTTPS connection (e.g. through urlopen() or HTTPConnection). An attacker who can control the url parameter passed to urlopen method in the urllib/urllib2 modules can inject CRLF sequences and HTTP headers by abusing the "host" part of the URL.

A flaw was found in Node.js versions before 6.15.0, 8.14.0, 10.14.0 and 11.3.0. A Denial of Service with large HTTP headers. By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer.

The c-ares function aresparsenaptrreply(), which is used for parsing NAPTR responses, could be triggered to read memory outside of the given input buffer if the passed in DNS response packet was crafted in a particular way.

It was discovered that the implementation of the PatternSyntaxException class in the Concurrency component of OpenJDK failed to sufficiently validate the 'index' value (to ensure it's not greater than the regular expression length) in the getMessage() method. An instance of the class with invalid index value, for example one created via deserialization on an untrusted input, could cause a Java application to use an excessive amount of memory.

A flaw was found in Node.js versions before 6.15.0, 8.14.0, 10.14.0 and 11.3.0. A hostname spoofing in URL parser for javascript protocol. If a Node.js application is using url.parse() to determine the URL hostname, that hostname can be spoofed by using a mixed case "javascript:" (e.g. "javAscript:") protocol (other protocols are not affected). If security decisions are made about the URL based on the hostname, they may be incorrect.
