Linux/Unix e-mail flaw leaves system wide open

Publication:TechworldDate:Aug 26 2005

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.
