The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5450-1 advisory.
Apache Subversion SVN authz protected copyfrom paths regression Subversion servers reveal ‘copyfrom’ paths that should be hidden according to configured path-based authorization (authz) rules. When a node has been copied from a protected location, users with access to the copy can see the ‘copyfrom’ path of the original. This also reveals the fact that the node was copied. Only the ‘copyfrom’ path is revealed; not its contents. Both httpd and svnserve servers are vulnerable. (CVE-2021-28544)
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)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
