Two security patches for Debian GNU/Linux has been released:
DSA-255-1 tcpdump -- infinite loopAndrew Griffiths and iDEFENSE Labs discovered a problem in tcpdump, a powerful tool for network monitoring and data acquisition. An attacker is able to send a specially crafted network packet which causes tcpdump to enter an infinite loop.
In addition to the above problem the tcpdump developers discovered a potential infinite loop when parsing malformed BGP packets. They also discovered a buffer overflow that can be exploited with certain malformed NFS packets.
For the stable distribution (woody) these problems have been fixed in version 3.6.2-2.3.
For the old stable distribution (potato) does not seem to be affected by this problem.
For the unstable distribution (sid) these problems have been fixed in version 3.7.1-1.2.
