Mandrakelinux Security Update Advisory _______________________________________________________________________

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. _______________________________________________________________________
