AlmaLinux 9.2 [TuxCare] Security Update: mod_md (ALMALINUX9.2:CLSA-2025:1767026442)

high Nessus Plugin ID 352010

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has a package installed that is affected by a vulnerability as referenced in the TuxCare ALMALINUX9.2:CLSA-2025:1767026442 advisory.

 - An integer overflow in the case of failed ACME certificate renewal leads, after a number of failures (~30 days in default configurations), to the backoff timer becoming 0. Attempts to renew the certificate then are repeated without delays until it succeeds. This issue affects Apache HTTP Server: from 2.4.30 before 2.4.66. Users are recommended to upgrade to version 2.4.66, which fixes the issue. (CVE-2025-55753)

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

Solution

Update the affected mod_md package based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2025:1767026442.
