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.(CVE-2022-24070)");
