Package        : subversion
CVE ID         : CVE-2020-17525
Debian Bug     : 982464

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.
