subversion vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 14.04 LTS
  • Ubuntu 12.04 LTS


Several security issues were fixed in Subversion.

Software Description

  • subversion - Advanced version control system


Lieven Govaerts discovered that the Subversion mod_dav_svn module incorrectly handled certain request methods when SVNListParentPath was enabled. A remote attacker could use this issue to cause the server to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS. (CVE-2014-0032)

Ben Reser discovered that Subversion did not correctly validate SSL certificates containing wildcards. A remote attacker could exploit this to perform a man in the middle attack to view sensitive information or alter encrypted communications. (CVE-2014-3522)

Bert Huijben discovered that Subversion did not properly handle cached credentials. A malicious server could possibly use this issue to obtain credentials cached for a different server. (CVE-2014-3528)
