Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 : OpenSSL vulnerabilities (USN-7786-1)

medium Nessus Plugin ID 266334

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7786-1 advisory.

 Stanislav Fort discovered that OpenSSL incorrectly handled memory when trying to decrypt CMS messages encrypted with password-based encryption. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2025-9230)

 Stanislav Fort discovered that OpenSSL had a timing side-channel in SM2 signature computations on ARM platforms. A remote attacker could possibly use this issue to recover private data. This issue only affected Ubuntu 25.04. (CVE-2025-9231)

 Stanislav Fort discovered that OpenSSL incorrectly handled memory during HTTP requests when no_proxy environment variable is set. An attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 25.04. (CVE-2025-9232)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
