    Linux/Unix e-mail flaw leaves system wide open

    Two serious security flaws have turned up in software widely distributed with Linux and Unix. The bugs affect Elm (Electronic Mail for Unix), a venerable e-mail client still used by many Linux and Unix sysadmins, and Mplayer, a cross-platform movie player that is one of the most popular of its kind on Linux. The Elm flaw involves a boundary error when the client reads an e-mail's "Expires" header. A specially crafted e-mail could exploit the bug to cause a buffer overflow and execute malicious code on a system, according to security researchers. Adding to the flaw's potential impact, exploit code has begun circulating on the Internet, according to FrSIRT, the French Security Incident Response Team, which published sample code on its site.

      Thanks Trip - a friend of mine is in the process of setting up a Linux server to act as a mail server - I'll make sure he sees this :)
