USN-1077-1: FUSE vulnerabilities

28 February 2011




It was discovered that FUSE would incorrectly follow symlinks when checking
mountpoints under certain conditions. A local attacker, with access to use
FUSE, could unmount arbitrary locations, leading to a denial of service.

Update instructions

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

Ubuntu 9.10
Ubuntu 8.04
Ubuntu 10.10
Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
