Debian Security Advisory DSA-4851-1 [email protected]
https://www.debian.org/security/ Salvatore Bonaccorso
February 13, 2021 https://www.debian.org/security/faq
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.
For the detailed security status of subversion please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/subversion
Further information about Debian Security Advisories, how to apply
these updates to your system and frequently asked questions can be
