Cvss 3 Severity Score

Description

In Apache Subversion versions up to and including 1.9.10, 1.10.4, 1.12.0, Subversion's svnserve server process may exit when a well-formed read-only request produces a particular answer. This can lead to disruption for users of the server.

From the Ubuntu Security Team

Ace Olszowka discovered that Subversion incorrectly handled certain svnserve requests. A remote attacker could possibly use this issue to cause svnserver to crash, resulting in a denial of service.
