GLSA-200905-03 : IPSec Tools: Denial of Service

medium Nessus Plugin ID 38884

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200905-03 (IPSec Tools: Denial of Service)

 The following vulnerabilities have been found in the racoon daemon as shipped with IPSec Tools:
 Neil Kettle reported that racoon/isakmp_frag.c is prone to a NULL pointer dereference (CVE-2009-1574).
 Multiple memory leaks exist in (1) the eay_check_x509sign() function in racoon/crypto_openssl.c and (2) racoon/nattraversal.c (CVE-2009-1632).
 Impact :

 A remote attacker could send specially crafted fragmented ISAKMP packets without a payload or exploit vectors related to X.509 certificate authentication and NAT traversal, possibly resulting in a crash of the racoon daemon.
 Workaround :

 There is no known workaround at this time.

Solution

All IPSec Tools users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-firewall/ipsec-tools-0.7.2'
