--------------------------------------------------------------------- Fedora Update Notification FEDORA-2005-082 2005-01-28 ---------------------------------------------------------------------

Product : Fedora Core 3 Name : openswan Version : 2.1.5 Release : 2.FC3.1 Summary : Openswan IPsec userland tools Description : 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.

--------------------------------------------------------------------- Update Information: 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.
