Package : viewvc
Vulnerability : several
Problem type : remote
Debian-specific: no
CVE ID : CVE-2009-5024 CVE-2012-3356 CVE-2012-3357 CVE-2012-4533

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

CVE-2012-3357: 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.

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.

Package : cups-pk-helper
Vulnerability : privilege escalation
Problem type : local
Debian-specific: no
CVE ID : CVE-2012-4510

privileges, wraps CUPS function calls in an insecure way. This could
lead to uploading sensitive data to a cups resource, or overwriting
specific files with the content of a cups resource. The user would have
to explicitly approve the action.

For the stable distribution (squeeze), this problem has been fixed in
version 0.1.0-3.

For the testing distribution (wheezy), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 0.2.3-1.

We recommend that you upgrade your cups-pk-helper packages.
