Serious Linux Security Flaw Found

Vulnerability is blamed for a recent high-profile attack. A serious vulnerability in the Linux 2.4 kernel has been discovered. The flaw allows users on a Linux machine to gain unlimited access privileges, according to a security advisory posted by developers of the noncommercial Debian Linux distribution. The bug affects versions of the Linux kernel prior to 2.4.23, and was the method used during a recent attack on Debian’s servers, according to the advisory. In that attack four Linux servers that hosted Debian’s bug tracking system, mailing lists, and various Web pages were compromised. The vulnerability can only be exploited by someone who has already been given a user account on the Linux machine, and does not affect users of every Linux system, said Linux creator Linus Torvalds in an e-mail interview.
