Description:
Two vulnerabilities were reported in tcpdump. A remote user can cause tcpdump to crash when in a certain configuration.
The tcpdump vendor reported that 'print-isakmp.c' does not properly validate user-supplied input in ISAKMP packets. A remote user can send a specially crafted packet to trigger the flaw.
Rapid7 subsequently issued an advisory [see the Message History] that provided additional details. The advisory indicated that the vulnerability applies only in the verbose packet display (-v) mode.
A remote user can send a specially crafted ISAKMP Delete payload with a large number of Security Protocol Identifiers (SPIs) to cause the tcpdump application to crash [CVE: CAN-2004-0183] due to a buffer overflow.
It is also reported that a remote user can send an ISAKMP Identification payload with a specially crafted payload length value that is less than 8 to cause tcpdump to crash [CVE: CAN-2004-0184].
The Rapid7 advisory provides additional details and is available at:

Impact:
A remote user can cause tcpdump to crash.

Solution:
Mandrake has released a fix.

Package name: tcpdump
Advisory ID: MDKSA-2004:030
Date: April 14th, 2004
Affected versions: 10.0, 9.1, 9.2, Corporate Server 2.1,
Multi Network Firewall 8.2
______________________________________________________________________
Problem Description:
A number of vulnerabilities were discovered in tcpdump versions prior
to 3.8.1 that, if fed a maliciously crafted packet, could be exploited
to crash tcpdump. These vulnerabilities include:
Remote attackers can cause a denial of service (crash) via ISAKMP packets
containing a Delete payload with a large number of SPI's, which causes
an out-of-bounds read. (CAN-2004-1083)
Integer underflow in the isakmp_id_print allows remote attackers to cause
a denial of service (crash) via an ISAKMP packet with an Identification
payload with a length that becomes less than 8 during byte order
conversion, which causes an out-of-bounds read. (CAN-2004-0184)
The updated packages are patched to correct these problems.
