Certifi 2023.07.22 removes root certificates from "e-Tugra" from the root store. These are in the process of being removed from Mozilla's trust store.

e-Tugra's root certificates are being removed pursuant to an investigation prompted by reporting of security issues in their systems. Conclusions of Mozilla's investigation can be found here.

An unspecified error in with TrustCor's ownership also operated a business that produced spyware in Certifi has an unknown impact and attack vector.

Eclipse Jetty is vulnerable to a denial of service, caused by an error when handling a request containing multiple Accept headers with a large number of quality parameters. By sending a specially-crafted request, a remote attacker could exploit this vulnerability to exhaust minutes of CPU time.

A security vulnerability was found in zlib. The flaw triggered a heap-based buffer in inflate in the inflate.c function via a large gzip header extra field. This flaw is only applicable in the call inflateGetHeader.

jsoup is a Java HTML parser, built for HTML editing, cleaning, scraping, and cross-site scripting (XSS) safety. jsoup may incorrectly sanitize HTML including javascript: URL expressions, which could allow XSS attacks when a reader subsequently clicks that link. If the non-default SafeList.preserveRelativeLinks option is enabled, HTML including javascript: URLs that have been crafted with control characters will not be sanitized. If the site that this HTML is published on does not set a Content Security Policy, an XSS attack is then possible. This issue is patched in jsoup 1.15.3. Users should upgrade to this version. Additionally, as the unsanitized input may have been persisted, old content should be cleaned again using the updated version. To remediate this issue without immediately upgrading: - disable SafeList.preserveRelativeLinks, which will rewrite input URLs as absolute URLs - ensure an appropriate Content Security Policy is defined. (This should be used regardless of upgrading, as a defence-in-depth best practice.)

In Spring Framework, versions 5.2.x prior to 5.2.15 and versions 5.3.x prior to 5.3.7, a WebFlux application is vulnerable to a privilege escalation: by (re)creating the temporary storage directory, a locally authenticated malicious user can read or modify files that have been uploaded to the WebFlux application, or overwrite arbitrary files with multipart request data.

An integer overflow issue was found in the redis ziplist data structure. The vulnerability involves modifying the default ziplist configuration parameters (hash-max-ziplist-entries, hash-max-ziplist-value, zset-max-ziplist-entries or zset-max-ziplist-value) to a very large value, and then constructing specially crafted commands to create very large ziplists. This flaw allows a remote attacker to corrupt the heap and potentially trigger remote code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

A flaw was found in redis. When using the Redis Lua Debugger, users can send malformed requests that cause the debugger’s protocol parser to read data beyond the actual buffer, potentially leading to an information disclosure.

An integer overflow issue was found in redis. The vulnerability involves changing the default "proto-max-bulk-len" and "client-query-buffer-limit" configuration parameters to very large values and constructing specially crafted large stream elements. This flaw allows a remote attacker to corrupt the heap and potentially trigger remote code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

A flaw was found in redis. When parsing an incoming Redis Standard Protocol (RESP) request, redis allocates memory according to user-specified values, which determine the number of elements (in the multi-bulk header) and size of each element (in the bulk header). This flaw allows an unauthenticated, remote user delivering specially crafted requests over multiple connections to cause the server to allocate a significant amount of memory, resulting in a denial of service. The highest threat from this vulnerability is to system availability.

A heap buffer overflow was found in redis. Specially crafted Lua scripts executing in Redis cause the heap-based Lua stack to overflow due to incomplete checks for this condition. This flaw allows a remote attacker to corrupt the heap and potentially trigger remote code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

An integer overflow issue was found in redis. The vulnerability involves changing the default "set-max-intset-entries" configuration parameter to a very large value and constructing specially crafted commands to manipulate sets. This flaw allows a remote attacker to leak arbitrary contents of the heap or potentially trigger remote code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

A vulnerability was discovered in Python. A quadratic algorithm exists when processing inputs to the IDNA (RFC 3490) decoder, such that a crafted unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor, which could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied hostname.

A memory leak flaw was found in Apache Tomcat, where an HTTP upgrade connection does not release for WebSocket connections once the WebSocket connection is closed. If a sufficient number of such requests are made, an OutOfMemoryError occurs, leading to a denial of service. The highest threat from this vulnerability is to system availability.

A null pointer de-reference was found in the way samba kerberos server handled missing sname in TGS-REQ (Ticket Granting Server - Request). An authenticated user could use this flaw to crash the samba server.

Eclipse Jetty could allow a remote attacker to obtain sensitive information, caused by a flaw in the ConcatServlet. By sending a specially-crafted request using a doubly encoded path, an attacker could exploit this vulnerability to obtain sensitive information from protected resources within the WEB-INF directory, and use this information to launch further attacks against the affected system.

An issue in the urllib.parse component of Python before 3.11.4 allows attackers to bypass blocklisting methods by supplying a URL that starts with blank characters.

A flaw was found in python. An improperly handled HTTP response in the HTTP client code of python may allow a remote attacker, who controls the HTTP server, to make the client script enter an infinite loop, consuming CPU time. The highest threat from this vulnerability is to system availability.

A flaw was found in Python, specifically within the urllib.parse module. This module helps break Uniform Resource Locator (URL) strings into components. The issue involves how the urlparse method does not sanitize input and allows characters like '\r' and '\n' in the URL path. This flaw allows an attacker to input a crafted URL, leading to injection attacks.

A flaw was found in systemd-journald. An out-of-bounds read when parsing a crafted syslog message that could lead to information disclosure.

A malicious server can serve excessive amounts of Set-Cookie: headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this, or other servers to which the cookies match, create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept, match and haven't expired. Due to cookie matching rules, a server on foo.example.com can set cookies that also would match for bar.example.com, making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method.

NTP is vulnerable to a denial of service, caused by an issue when relying on unauthenticated IPv4 time sources in ntpd. By predicting transmit timestamps for use in spoofed packets, a remote attacker could exploit this vulnerability to cause the daemon to crash or system time change.

Eclipse Jetty could allow a remote attacker to hijack a user's session, caused by a flaw in the FileSessionDataStore. An attacker could exploit this vulnerability to gain access to another user's session.

An issue was discovered in splithugepmd in mm/hugememory.c in the Linux kernel before 5.7.5. The copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check, aka CID-c444eb564fb1.
