Debian DSA-2672-1 : kfreebsd-9 - interpretation conflict

high Nessus Plugin ID 66548

Language:

Synopsis

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

Description

Adam Nowacki discovered that the new FreeBSD NFS implementation processes a crafted READDIR request which instructs to operate a file system on a file node as if it were a directory node, leading to a kernel crash or potentially arbitrary code execution.

The kfreebsd-8 kernel in the oldstable distribution (squeeze) does not enable the new NFS implementation. The Linux kernel is not affected by this vulnerability.

Solution

Upgrade the kfreebsd-9 packages.

For the stable distribution (wheezy), this problem has been fixed in version 9.0-10+deb70.1.
