USN-1382-1: Light Display Manager vulnerability

5 March 2012

Light Display Manager would allow unintended access to file descriptors.




Austin Clements discovered that Light Display Manager incorrectly leaked
file descriptors to child processes. A local attacker can use this to
bypass intended permissions and write to the log file, cause a denial of
service, or possibly have another unknown impact.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.10

After a standard system update you need to reboot your computer to make
all the necessary changes.
