MDKSA-2003:027 - Updated tcpdump packages fix denial of service vulnerabilities

by Nikola Strahija on March 3rd, 2003 By sending a specially crafted network packet, an attacker is able to to cause tcpdump to enter an infinite loop.


Package name: tcpdump
Advisory ID: MDKSA-2003:027
Date: March 3rd, 2003

Affected versions: 8.1, 8.2, 9.0, Corporate Server 2.1,
Multi Network Firewall 8.2,
Single Network Firewall 7.2
________________________________________________________________________

Problem Description:

A vulnerability was discovered by Andrew Griffiths and iDEFENSE Labs
in the tcpdump program. By sending a specially crafted network packet,
an attacker is able to to cause tcpdump to enter an infinite loop. In
addition, the tcpdump developers found a potential infinite loop when
tcpdump parses malformed BGP packets. A buffer overflow was also
discovered that can be exploited with certain malformed NFS packets.
