Subversion

The Discovery

Several important security vulnerabilities have been found in the Subversion version control system. It was discovered that Subversion servers reveal 'copyfrom' paths that should be hidden according to configured path-based authorization (authz) rules (CVE-2021-28544), and that Subversion's mod_dav_svn is prone to a use-after-free vulnerability when looking up path-based authorization rules (CVE-2022-24070).

The Impact

These issues could result in denial of service (crash of HTTPD worker handling the request) and memory corruption.

The Fix

A Subversion security update fixes these flaws. Update now to protect the security, integrity and availability of your systems.
