Debian Security Advisory DSA-206-1 security@debian.org
http://www.debian.org/security/ Wichert Akkerman
December 10, 2002
------------------------------------------------------------------------


Package : tcpdump
Problem type : incorrect bounds checking
Debian-specific: no

The BGP decoding routines for tcpdump used incorrect bounds checking
when copying data. This could be abused by introducing malicious traffic
on a sniffed network for a denial of service attack against tcpdump,
or possibly even remote code execution.

This has been fixed in version 3.6.2-2.2.


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

Obtaining updates:

By hand:
wget URL
will fetch the file for you.
dpkg -i FILENAME.deb
will install the fetched file.

With apt:
deb http://security.debian.org/ stable/updates main
added to /etc/apt/sources.list will provide security updates

Additional information can be found on the Debian security webpages
at http://www.debian.org/security/
