AlmaLinux 9.2 [TuxCare] Security Update: varnish / varnish-devel / varnish-docs Multiple Vulnerabilities (ALMALINUX9.2:CLSA-2025:1763374645)

medium Nessus Plugin ID 361729

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-2025:1763374645 advisory.

 - Varnish Cache before 7.3.2 and 7.4.x before 7.4.3 (and before 6.0.13 LTS), and Varnish Enterprise 6 before 6.0.12r6, allows credits exhaustion for an HTTP/2 connection control flow window, aka a Broke Window Attack. (CVE-2024-30156)

 - Varnish Cache before 7.6.3 and 7.7 before 7.7.1, and Varnish Enterprise before 6.0.13r14, allow client- side desync via HTTP/1 requests, because the product incorrectly permits CRLF to be skipped to delimit chunk boundaries. (CVE-2025-47905)

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

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2025:1763374645.
