FreeBSD-SA-01:20 Security Advisory

by Phiber on February 8th, 2001 The mars_nwe port, versions prior to 0.99.b19_1, contains a remote format string vulerability. Because of this vulnerability, a malicious remote user sending specially-crafted packets may be able to execute arbitrary code on the local system, potentially gaining root access....

The mars_nwe port is not installed by default, nor is it "part of
FreeBSD" as such: it is part of the FreeBSD ports collection, which
contains over 4500 third-party applications in a ready-to-install
format. The ports collections shipped with FreeBSD 3.5.1 and 4.2
contain this problem since it was discovered after the releases.

FreeBSD makes no claim about the security of these third-party
applications, although an effort is underway to provide a security
audit of the most security-critical ports.

Quick Fix:

Upgrade your entire ports collection and rebuild the mars_nwe port. (another solution for fixing this vulnerability is in the advisory, so download it!)
