Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2022-076 advisory.

 A use-after-free vulnerability was found in Subversion in the mod_dav_svn Apache HTTP server (HTTPd) module. While looking up path-based authorization (authz) rules, multiple calls to the post_config hook can invalidate cached pointers to object-pools, which Subversion subsequently uses. This issue crashes the single HTTPd worker thread or the entire HTTPd server process, depending on the configuration of the Apache HTTPd server. (CVE-2022-24070)

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

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

Solution

Run 'dnf update --releasever=2022.0.20220518 subversion' to update your system.
