Amazon Linux 2022 : python3-subversion, subversion, subversion-devel (ALAS2022-2022-149)

medium Nessus Plugin ID 166120

Synopsis

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

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-149 advisory.

 A flaw was found in Subversion. When using path-based authorization (authz), the helper function detect_changed() does not omit potentially sensitive information from log messages. In particular, if a node is copied from a protected location, its copyfrom path (the path to the protected location) is reported even when omission should occur. (CVE-2021-28544)

 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 these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'dnf update subversion --releasever=2022.0.20221012' to update your system.
