- Date Reported:
- 18 Oct 2016
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 840443.
In Mitre's CVE dictionary: CVE-2016-7949, CVE-2016-7950.
- More information:
Tobias Stoeckmann from the OpenBSD project has discovered a number of issues in the way various X client libraries handle the responses they receive from servers. Insufficient validation of data from the X server could cause out of boundary memory writes in the libXrender library potentially allowing the user to escalate their privileges.
For Debian 7
Wheezy, these problems have been fixed in version 1:0.9.7-1+deb7u3.
We recommend that you upgrade your libxrender packages.
