CVE-2022-24070
Published: 12 April 2021
Subversion's mod_dav_svn is vulnerable to memory corruption. While looking up path-based authorization rules, mod_dav_svn servers may attempt to use memory which has already been freed. Affected Subversion mod_dav_svn servers 1.10.0 through 1.14.1 (inclusive). Servers that do not use mod_dav_svn are not affected.
From the Ubuntu Security Team
Thomas Weißschuh discovered that subversion servers did not properly handle memory in certain configurations. A remote attacker could potentially use this issue to cause a denial of service or other unspecified impact.
