Debian: Security update for ViewVC

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

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

Updated packages are available from security.debian.org.
