Package        : subversion
CVE ID         : CVE-2021-28544 CVE-2022-24070

Several vulnerabilities were discovered in Subversion, a version control
system.

CVE-2021-28544

    Evgeny Kotkov reported that Subversion servers reveal 'copyfrom'
    paths that should be hidden according to configured path-based
    authorization (authz) rules.

CVE-2022-24070

    Thomas Weissschuh reported that Subversion's mod_dav_svn is prone to
    a use-after-free vulnerability when looking up path-based
    authorization rules, which can result in denial of service (crash of
    HTTPD worker handling the request).

For the oldstable distribution (buster), these problems have been fixed
in version 1.10.4-1+deb10u3.

For the stable distribution (bullseye), these problems have been fixed in
version 1.14.1-3+deb11u1.

We recommend that you upgrade your subversion packages.
