X.Org Security Advisory - libXfont suffers from a stack buffer overflow vulnerability. A BDF font file containing a longer than expected string could overflow the buffer on the stack. As libXfont is used to read user-specified font files in all X servers distributed by X.Org, including the Xorg server which is often run with root privileges or as setuid-root in order to access hardware, this bug may lead to an unprivileged user acquiring root privileges in some systems.
