More information:

Anders Kaseorg discovered that afuse, an automounting file system in user-space, did not properly escape meta characters in paths. This allowed a local attacker with read access to the filesystem to execute commands as the owner of the filesystem.

For the stable distribution (etch), this problem has been fixed in version 0.1.1-1+etch4.

For the unstable distribution (sid), this problem has been fixed in version 0.2-3.

We recommend that you upgrade your afuse (0.1.1-1+etch4) package.

Fixed in:

Debian GNU/Linux 4.0 (etch)
