More information:

Several vulnerabilities were found in ViewVC, a web interface for CVS and Subversion repositories.

  • CVE-2009-5024

    Remote attackers can bypass the cvsdb row_limit configuration setting, and consequently conduct resource-consumption attacks via the limit parameter.

  • CVE-2012-3356

    The remote Subversion views functionality does not properly perform authorization, which allows remote attackers to bypass intended access restrictions.

  • CVE-2012-3357

    The Subversion revision view does not properly handle log messages when a readable path is copied from an unreadable path, which allows remote attackers to obtain sensitive information.

  • CVE-2012-4533

    function name lines returned by diff are not properly escaped, allowing attackers with commit access to perform cross site scripting.

For the stable distribution (squeeze), these problems have been fixed in version 1.1.5-1.1+squeeze2.

For the testing distribution (wheezy), these problems will be fixed soon.

For the unstable distribution (sid), these problems have been fixed in version 1.1.5-1.4.

We recommend that you upgrade your viewvc packages.
