Open-source programmers have released a patch to a major vulnerability in the Samba software. Samba is widely used to let computers running the Microsoft Windows operating system tap into files on Linux machines, and vice versa. The problem, which affects versions 2.2.2 through 2.2.6 but is fixed in 2.2.7, could let an attacker gain control over a computer system.
Major editions of Linux--including Red Hat, SuSE, MandrakeSoft, Debian, Turbolinux and Conectiva--all have links to their patches posted at the Mitre list.
