Debian Security Advisory DSA 850-1 security@debian.org

- --------------------------------------------------------------------------

Package : tcpdump
Vulnerability : infinite loop
Problem type : remote
Debian-specific: no
CVE ID : CAN-2005-1279

"Vade 79" discovered that the BGP dissector in tcpdump, a powerful
tool for network monitoring and data acquisition, does not properly
handle RT_ROUTING_INFO. A specially crafted BGP packet can cause a
denial of service via an infinite loop.

For the old stable distribution (woody) this problem has been fixed in
version 3.6.2-2.9.

For the stable distribution (sarge) this problem has been fixed in
version 3.8.3-4.

For the unstable distribution (sid) this problem has been fixed in
version 3.8.3-4.

We recommend that you upgrade your tcpdump package.


Upgrade Instructions
