Ubuntu Security Notice USN-2316-1
14th August, 2014
subversion vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
Ubuntu 14.04 LTS
Ubuntu 12.04 LTS
Summary
Several security issues were fixed in Subversion.
Software description
subversion - Advanced version control system
Details
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)
