Vulnerability Assessment Details

Fedora Core 3 2005-082: openswan

Vulnerability Assessment Summary
Check for the version of the openswan package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory FEDORA-2005-082 (openswan).

Openswan is a free implementation of IPSEC & IKE for Linux.

IPsec is Internet Protocol Security and uses strong cryptography to
provide both authentication and encryption services. These services
permit you to build secure tunnels through untrusted networks.
Everything passing through the untrusted net is encrypted by the ipsec
gateway machine and decrypted by the gateway at the other end of the
tunnel. The resulting tunnel is a virtual private network or VPN.

This package contains the daemons and userland tools for setting up
Openswan on a kernel with the 2.6 native IPsec code.

Update Information:
This erratum fixes the remote exploitation of a stack based buffer
overflow vulnerability in Xelerance Corp.'s Openswan, which could
permit attackers to execute arbitrary code.

The vulnerability specifically exists due to a lack of bounds checking
in the pluto application when Openswan is compiled with XAUTH and PAM
support.

The Common Vulnerabilities and Exposures project has assigned
the name CVE-2005-0162 to this problem.
