- Date Reported:
- 13 Feb 2021
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 982464.
In Mitre's CVE dictionary: CVE-2020-17525.
- More information:
Thomas Akesson discovered a remotely triggerable vulnerability in the mod_authz_svn module in Subversion, a version control system. When using in-repository authz rules with the AuthzSVNReposRelativeAccessFile option an unauthenticated remote client can take advantage of this flaw to cause a denial of service by sending a request for a non-existing repository URL.
For the stable distribution (buster), this problem has been fixed in version 1.10.4-1+deb10u2.
We recommend that you upgrade your subversion packages.
