Debian DSA-116-1 : cfs - buffer overflow

high Nessus Plugin ID 14953

Synopsis

The remote Debian host is missing a security-related update.

Description

Zorgon found several buffer overflows in cfsd, a daemon that pushes encryption services into the Unix(tm) file system. We are not yet sure if these overflows can successfully be exploited to gain root access to the machine running the CFS daemon. However, since cfsd can easily be forced to die, a malicious user can easily perform a denial of service attack to it.

Solution

Upgrade the cfs package immediately.

This problem has been fixed in version 1.3.3-8.1 for the stable Debian distribution and in version 1.4.1-5 for the testing and unstable distribution of Debian.
