Synopsis

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.

Solution

Upgrade the subversion packages.

For the oldstable distribution (stretch), these problems have been fixed in version 1.9.5-1+deb9u4.

For the stable distribution (buster), these problems have been fixed in version 1.10.4-1+deb10u1.
