- Date Reported:
- 23 Oct 2012
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2009-5024, CVE-2012-3356, CVE-2012-3357, CVE-2012-4533.
- More information:
Several vulnerabilities were found in ViewVC, a web interface for CVS and Subversion repositories.
Remote attackers can bypass the cvsdb row_limit configuration setting, and consequently conduct resource-consumption attacks via the limit parameter.
The remote Subversion views functionality does not properly perform authorization, which allows remote attackers to bypass intended access restrictions.
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.
function namelines 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.
