USN-429-1: tcpdump vulnerability

6 March 2007

tcpdump vulnerability



Moritz Jodeit discovered that tcpdump had an overflow in the 802.11
packet parser. Remote attackers could send specially crafted packets,
crashing tcpdump, possibly leading to a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 6.10
  • tcpdump - 3.9.4-4ubuntu0.1
Ubuntu 6.06
  • tcpdump - 3.9.4-2ubuntu0.1
Ubuntu 5.10
  • tcpdump - 3.9.1-1ubuntu1.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.
