Security Flaws Found in Mplayer and Elm
Two serious security flaws have turned up in software widely distributed with Linux and Unix. The bugs affect Electronic Mail for Unix (Elm), a venerable e-mail client still used by many Linux and Unix systems administrators, 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.
The bug in Mplayer is the latest media-player bug to plague systems administrators. Widely used desktop applications such as media players are more difficult to patch than server-side bugs, because there are many times more copies in use, often without the knowledge of IT managers.
The flaw affects Mplayer versions 1.0pre7 and earlier and hasn't been patched, according to an advisory from FrSIRT.
