Fedora Core 3 FEDORA-2005-082 Critical: Openswan Buffer Overflow Exploit

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

allow 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.

This erratum fixes the remote exploitation of a stack based buffer

overflow vulnerability in Xelerance Corp.'s Openswan, which could

allow 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 CAN-2005-0162 to this problem.

- fixed possible xauth/PAM buffer overflow. (bug 146287)
