Debian: DSA-2952-1 Critical: FreeBSD Denial of Service Threat

Several vulnerabilities have been discovered in the FreeBSD kernel that may
lead to a denial of service or possibly disclosure of kernel memory. The Common
Vulnerabilities and Exposures project identifies the following problems:

CVE-2014-1453

A remote, authenticated attacker could cause the NFS server become
deadlocked, resulting in a denial of service.

CVE-2014-3000:

An attacker who can send a series of specifically crafted packets with a
connection could cause a denial of service situation by causing the kernel
to crash.

Additionally, because the undefined on stack memory may be overwritten by
other kernel threads, while difficult, it may be possible for an attacker
to construct a carefully crafted attack to obtain portion of kernel memory
via a connected socket. This may result in the disclosure of sensitive
information such as login credentials, etc. before or even without
crashing the system.

CVE-2014-3880

A local attacker can trigger a kernel cr...
