Linux kernel vulnerability

Releases

Details

USN-319-1 fixed a Linux kernel vulnerability in Ubuntu 6.06 LTS. This
followup advisory provides the corresponding updates for Ubuntu 5.04
and 5.10.

For reference, these are the details of the original USN:

of the /proc file system. A local attacker could exploit this to
execute arbitrary code with full root privileges.
