The Tungstenite crate through 0.20.0 for Rust allows remote attackers to cause a denial of service (minutes of CPU consumption) via an excessive length of an HTTP header in a client handshake. The length affects both how many times a parse is attempted (e.g., thousands of times) and the average amount of data for each parse attempt (e.g., millions of bytes).

Buffer Overflow vulnerability in JerryScript version 3.0, allows remote attackers to execute arbitrary code via ecma_stringbuilder_append_raw component at /jerry-core/ecma/base/ecma-helpers-string.c.

In the Unbreakable Enterprise Kernel (UEK), the RDS module in UEK has two setsockopt(2) options, RDS_CONN_RESET and RDS6_CONN_RESET, that are not re-entrant. A malicious local user with CAP_NET_ADMIN can use this to crash the kernel. CVSS 3.1 Base Score 5.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).

Jenkins creates a temporary file when a plugin is deployed directly from a URL. Jenkins 2.423 and earlier, LTS 2.414.1 and earlier creates this temporary file in the system temporary directory with the default permissions for newly created files. If these permissions are overly permissive, they may allow attackers with access to the Jenkins controller file system to read and write the file before it is installed in Jenkins, potentially resulting in arbitrary code execution. This vulnerability only affects operating systems using a shared temporary directory for all users (typically Linux). Additionally, the default permissions for newly created files generally only allow attackers to read the temporary file, but not write to it. This issue complements SECURITY-2823, which affected plugins uploaded from an administrator’s computer. Jenkins 2.424, LTS 2.414.2 creates the temporary file in a subdirectory with more restrictive permissions. As a workaround, you can change your default ...

In Jenkins 2.423 and earlier, LTS 2.414.1 and earlier, uploaded files processed via the Stapler web framework and the Jenkins API `MultipartFormDataParser` create temporary files in the system temporary directory with the default permissions for newly created files. If these permissions are overly permissive, attackers with access to the system temporary directory may be able to read and write the file before it is used. This vulnerability only affects operating systems using a shared temporary directory for all users (typically Linux). Additionally, the default permissions for newly created files generally only allow attackers to read the temporary file, but not write to it. Jenkins 2.424, LTS 2.414.2 creates the temporary files in a subdirectory with more restrictive permissions. As a workaround, you can change your default temporary-file directory using the Java system property `java.io.tmpdir`, if you’re concerned about this issue but unable to immediately update Jenkins.

A cross-site request forgery (CSRF) vulnerability in Jenkins Build Failure Analyzer Plugin 2.4.1 and earlier allows attackers to delete Failure Causes.

Jenkins 2.423 and earlier, LTS 2.414.1 and earlier creates a temporary file in the system temporary directory with the default permissions for newly created files when installing a plugin from a URL, potentially allowing attackers with access to the system temporary directory to replace the file before it is installed in Jenkins, potentially resulting in arbitrary code execution.

Jenkins 2.50 through 2.423 (both inclusive), LTS 2.60.1 through 2.414.1 (both inclusive) does not exclude sensitive build variables (e.g., password parameter values) from the search in the build history widget, allowing attackers with Item/Read permission to obtain values of sensitive variables used in builds by iteratively testing different characters until the correct sequence is discovered.

A cross-site request forgery (CSRF) vulnerability in Jenkins Build Failure Analyzer Plugin 2.4.1 and earlier allows attackers to connect to an attacker-specified hostname and port using attacker-specified username and password.
