Ubuntu Security Notice 7018-1 - Robert Merget, Marcus Brinkmann, Nimrod Aviram, and Juraj Somorovsky discovered that certain Diffie-Hellman ciphersuites in the TLS specification and implemented by OpenSSL contained a flaw. A remote attacker could possibly use this issue to eavesdrop on encrypted communications. This was fixed in this update by removing the insecure ciphersuites from OpenSSL. Paul Kehrer discovered that OpenSSL incorrectly handled certain input lengths in EVP functions. A remote attacker could possibly use this issue to cause OpenSSL to crash, resulting in a denial of service.

Debian Linux Security Advisory 5770-1 - Shang-Hung Wan discovered multiple vulnerabilities in the Expat XML parsing C library, which could result in denial of service or potentially the execution of arbitrary code.

Ubuntu Security Notice 7000-2 - USN-7000-1 fixed vulnerabilities in Expat. This update provides the corresponding updates for Ubuntu 22.04 LTS. Shang-Hung Wan discovered that Expat did not properly handle certain function calls when a negative input length was provided. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 7017-1 - Iggy Frankovic discovered that Quagga incorrectly handled certain BGP messages. A remote attacker could possibly use this issue to cause Quagga to crash, resulting in a denial of service.

Ubuntu Security Notice 7016-1 - Iggy Frankovic discovered that FRR incorrectly handled certain BGP messages. A remote attacker could possibly use this issue to cause FRR to crash, resulting in a denial of service.

A vulnerability was found in the ilab model serve component, where improper handling of the best_of parameter in the vllm JSON web API can lead to a Denial of Service (DoS). The API used for LLM-based sentence or chat completion accepts a best_of parameter to return the best completion from several options. When this parameter is set to a large value, the API does not handle timeouts or resource exhaustion properly, allowing an attacker to cause a DoS by consuming excessive system resources. This leads to the API becoming unresponsive, preventing legitimate users from accessing the service.

A flaw was found in the vLLM library. A completions API request with an empty prompt will crash the vLLM API server, resulting in a denial of service.

Ubuntu Security Notice 7001-2 - USN-7001-1 fixed vulnerabilities in xmltol library. This update provides the corresponding updates for Ubuntu 24.04 LTS. Shang-Hung Wan discovered that Expat, contained within the xmltok library, did not properly handle certain function calls when a negative input length was provided. An attacker could use this issue to cause a denial of service or possibly execute arbitrary code.
