Details

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

• fuse-utils - 2.7.4-1.1ubuntu4.5

Ubuntu 8.04

• fuse-utils - 2.7.2-1ubuntu2.3

Ubuntu 10.10

• fuse-utils - 2.8.4-1ubuntu1.3

Ubuntu 10.04

• fuse-utils - 2.8.1-1.1ubuntu3.1

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