Debian DSA-2922-1 : strongswan - security update

medium Nessus Plugin ID 73867

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

A vulnerability has been found in the ASN.1 parser of strongSwan, an IKE/IPsec suite used to establish IPsec protected links.

By sending a crafted ID_DER_ASN1_DN ID payload to a vulnerable pluto or charon daemon, a malicious remote user can provoke a NULL pointer dereference in the daemon parsing the identity, leading to a crash and a denial of service.

Solution

Upgrade the strongswan packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 4.4.1-5.6.

For the stable distribution (wheezy), this problem has been fixed in version 4.5.2-1.5+deb7u4.
