Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1778613560 advisory.

 - When folding a long comment in an email header containing exclusively unfoldable characters, the parenthesis would not be preserved. This could be used for injecting headers into email messages where addresses are user-controlled and not sanitized. (CVE-2025-11468)

 - User-controlled data URLs parsed by urllib.request.DataHandler allow injecting headers through newlines in the data URL mediatype. (CVE-2025-15282)

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