Jenkins Script Security Plugin provides a sandbox feature that allows low privileged users to define scripts, including Pipelines, that are generally safe to execute. Calls to code defined inside a sandboxed script are intercepted, and various allowlists are checked to determine whether the call is to be allowed. Multiple sandbox bypass vulnerabilities exist in Script Security Plugin 1335.vf07d9ce377a_e and earlier: - Crafted constructor bodies that invoke other constructors can be used to construct any subclassable type via implicit casts. - Sandbox-defined Groovy classes that shadow specific non-sandbox-defined classes can be used to construct any subclassable type. These vulnerabilities allow attackers with permission to define and run sandboxed scripts, including Pipelines, to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM. - These issues are caused by an incomplete fix of [SECURITY-2824](https://www.jenkins.io/security/ad...

Issues addressed include denial of service and file overwrite vulnerabilities.

Jenkins HTML Publisher Plugin 1.16 through 1.32 (both inclusive) does not properly sanitize input, allowing attackers with Item/Configure permission to implement cross-site scripting (XSS) attacks and to determine whether a path on the Jenkins controller file system exists.

### Impact If an HTTP/2 connection gets TCP congested, when an idle timeout occurs the HTTP/2 session is marked as closed, and then a GOAWAY frame is queued to be written. However it is not written because the connection is TCP congested. When another idle timeout period elapses, it is then supposed to hard close the connection, but it delegates to the HTTP/2 session which reports that it has already been closed so it does not attempt to hard close the connection. This leaves the connection in ESTABLISHED state (i.e. not closed), TCP congested, and idle. An attacker can cause many connections to end up in this state, and the server may run out of file descriptors, eventually causing the server to stop accepting new connections from valid clients. The client may also be impacted (if the server does not read causing a TCP congestion), but the issue is more severe for servers. ### Patches Patched versions: * 9.4.54 * 10.0.20 * 11.0.20 * 12.0.6 ### Workarounds Disable HTTP/2 and HTTP/...

Red Hat Security Advisory 2024-0625-03 - An update for libssh is now available for Red Hat Enterprise Linux 8.8 Extended Update Support.

### Impact In runc 1.1.11 and earlier, due to an internal file descriptor leak, an attacker could cause a newly-spawned container process (from `runc exec`) to have a working directory in the host filesystem namespace, allowing for a container escape by giving access to the host filesystem ("attack 2"). The same attack could be used by a malicious image to allow a container process to gain access to the host filesystem through `runc run` ("attack 1"). Variants of attacks 1 and 2 could be also be used to overwrite semi-arbitrary host binaries, allowing for complete container escapes ("attack 3a" and "attack 3b"). Strictly speaking, while attack 3a is the most severe from a CVSS perspective, attacks 2 and 3b are arguably more dangerous in practice because they allow for a breakout from inside a container as opposed to requiring a user execute a malicious image. The reason attacks 1 and 3a are scored higher is because being able to socially engineer users is treated as a given for UI:R ...

Red Hat Security Advisory 2024-0538-03 - An update for libssh is now available for Red Hat Enterprise Linux 8.6 Extended Update Support. Issues addressed include bypass and null pointer vulnerabilities.

Jenkins Matrix Project Plugin 822.v01b_8c85d16d2 and earlier does not sanitize user-defined axis names of multi-configuration projects, allowing attackers with Item/Configure permission to create or replace any config.xml files on the Jenkins controller file system with content not controllable by the attackers.

Jenkins Git server Plugin 99.va_0826a_b_cdfa_d and earlier does not disable a feature of its command parser that replaces an '@' character followed by a file path in an argument with the file's contents, allowing attackers with Overall/Read permission to read content from arbitrary files on the Jenkins controller file system.

Gentoo Linux Security Advisory 202312-17 - Multiple vulnerabilities have been discovered in OpenSSH, the worst of which could lead to code execution. Versions greater than or equal to 9.6_p1 are affected.

Debian Linux Security Advisory 5586-1 - Several vulnerabilities have been discovered in OpenSSH, an implementation of the SSH protocol suite.

Ubuntu Security Notice 6561-1 - Fabian Bäumer, Marcus Brinkmann, Joerg Schwenk discovered that the SSH protocol was vulnerable to a prefix truncation attack. If a remote attacker was able to intercept SSH communications, extension negotiation messages could be truncated, possibly leading to certain algorithms and features being downgraded. This issue is known as the Terrapin attack. This update adds protocol extensions to mitigate this issue.

Ubuntu Security Notice 6560-1 - Fabian Bäumer, Marcus Brinkmann, Joerg Schwenk discovered that the SSH protocol was vulnerable to a prefix truncation attack. If a remote attacker was able to intercept SSH communications, extension negotiation messages could be truncated, possibly leading to certain algorithms and features being downgraded.

This issue only affected Ubuntu 22.04 LTS, and Ubuntu 23.04.
