CVE-2024-46901: Apache Subversion via mod_dav_svn can be crashed
CVE-2024-46901 · published 1 year ago
Summary
If you host Subversion repositories using the mod_dav_svn web interface, a user who can commit changes could add a specially crafted file name containing hidden control characters. That commit can corrupt the repository and stop other users from accessing it. Update Subversion to version 1.14.5 (or later) to stop this from happening.
What to do
- Update debian subversion to version 1.14.2-4+deb12u1.
- Update debian subversion to version 1.14.5-1.
- Update subversion to version 1.14.5-r0.
- Update apache subversion to version 1.14.5 or later.

Original advisory text
Apache Subversion: mod_dav_svn denial-of-service via control characters in paths
Insufficient validation of filenames against control characters in Apache Subversion repositories served via mod_dav_svn allows authenticated users with commit access to commit a corrupted revision, leading to disruption for users of the repository. All versions of Subversion up to and including Subversion 1.14.4 are affected if serving repositories via mod_dav_svn. Users are recommended to upgrade to version 1.14.5, which fixes this issue. Repositories served via other access methods are not affected.
