A flaw was found in the math/big package of Go's standard library that causes a denial of service. Applications written in Go that use math/big via cryptographic packages, including crypto/rsa and crypto/x509, are vulnerable and can potentially cause panic via a crafted certificate chain. The highest threat from this vulnerability is to system availability.

A flaw was found in the Go encoding/binary package. Certain invalid inputs to the ReadUvarint or the ReadVarint causes those functions to read an unlimited number of bytes from the ByteReader argument before returning an error. This flaw possibly leads to processing more input than expected. The highest threat from this vulnerability is to system availability.

A flaw was found in the way the readObject() method of the MethodType class in the Libraries component of OpenJDK checked argument types. An untrusted Java application or applet could use this flaw to bypass Java sandbox restrictions.

A flaw was found in the boundary checks in the java.nio buffer classes in the Libraries component of OpenJDK, where it is bypassed in certain cases. This flaw allows an untrusted Java application or applet o bypass Java sandbox restrictions.

A flaw was found in FasterXML Jackson Databind which did not have entity expansion secured properly making it vulnerable to XML external entity (XXE). This vulnerability is similar to CVE-2019-10172. The primary threat from this flaw is data integrity.

A deserialization flaw was discovered in Apache Tomcat's use of a FileStore. An attacker can exploit the flaw if all of the following are true: An attacker is able to control the contents and name of a file on the server. The server is configured to use the PersistenceManager with a FileStore. The PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker-provided object to be deserialized. The attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over. If all these conditions are true, the attacker can use a specifically crafted request to trigger Remote Code Execution through deserialization of the file under their control.

This flaw affects the following Tomcat versions: 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54, and 7.0.0 to 7.0.103.

A flaw was found in all resteasy 3.x.x versions prior to 3.12.0.Final and all resteasy 4.x.x versions prior to 4.6.0.Final, where an improper input validation results in returning an illegal header that integrates into the server's response. This flaw may result in an injection, which leads to unexpected behavior when the HTTP response is constructed.

Apache Ant could allow a remote authenticated attacker to bypass security restrictions, caused by an insecure temporary file flaw. By sending a specially-crafted request, an attacker could exploit this vulnerability to inject modified source files into the build process.

An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack.

A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctpdestroysock is called without socknet(sk)->sctp.addrwqlock then an element is removed from the autoasconfsplist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPFCGROUPINETSOCKCREATE is attached which denies creation of some SCTP socket.

A flaw was found in xorg-x11-server in versions before 1.20.11. An integer underflow can occur in xserver which can lead to a local privilege escalation. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in mupdf 1.18.0. Double free of object during linearization may lead to memory corruption and other potential consequences.

A heap-based buffer overflow was found in the way sudo parses command line arguments.

As per the researcher this vulnerability:

- is exploitable by any local user (normal users and system users, sudoers and non-sudoers), without authentication (i.e., the attacker does not need to know the user's password);

- was introduced in July 2011 (commit 8255ed69), and affects all legacy versions from 1.8.2 to 1.8.31p2 and all stable versions from 1.9.0 to 1.9.5p1, in their default configuration.

This could lead to privilege escalation.

An issue was discovered in the Linux kernel through 5.11.6. fastrpcinternalinvoke in drivers/misc/fastrpc.c does not prevent user applications from sending kernel RPC messages, aka CID-20c40794eb85. This is a related issue to CVE-2019-2308.

Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers.

In Wireshark 3.2.0 to 3.2.1, 3.0.0 to 3.0.8, and 2.6.0 to 2.6.14, the LTE RRC dissector could leak memory. This was addressed in epan/dissectors/packet-lte-rrc.c by adjusting certain append operations.

In Wireshark 3.2.0 to 3.2.1, 3.0.0 to 3.0.8, and 2.6.0 to 2.6.14, the WiMax DLMAP dissector could crash. This was addressed in plugins/epan/wimax/msgdlmap.c by validating a length field.

In Wireshark 3.2.0 to 3.2.1, 3.0.0 to 3.0.8, and 2.6.0 to 2.6.14, the EAP dissector could crash. This was addressed in epan/dissectors/packet-eap.c by using more careful sscanf parsing.

An issue was discovered in Pure-FTPd 1.0.49. An out-of-bounds (OOB) read has been detected in the purestrcmp function in utils.c.

Sympa 6.2.38 through 6.2.52 allows remote attackers to cause a denial of service (disk consumption from temporary files, and a flood of notifications to listmasters) via a series of requests with malformed parameters.
