Debian DLA-1903-1 : subversion security update

high Nessus Plugin ID 128395

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities were discovered in Subversion, a version control system. The Common Vulnerabilities and Exposures project identifies the following problems :

CVE-2018-11782

Ace Olszowka reported that the Subversion's svnserve server process may exit when a well-formed read-only request produces a particular answer, leading to a denial of service.

CVE-2019-0203

Tomas Bortoli reported that the Subversion's svnserve server process may exit when a client sends certain sequences of protocol commands.
If the server is configured with anonymous access enabled this could lead to a remote unauthenticated denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 1.8.10-6+deb8u7.

We recommend that you upgrade your subversion packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
