Subject: Immunix Secured OS 7.3 XFree86 update
-----------------------------------------------------------------------
Immunix Secured OS Security Advisory
Packages updated: XFree86
Affected products: Immunix OS 7.3
Bugs fixed: CAN-2004-0083, CAN-2004-0084, CAN-2004-0106
Date: Thu Feb 12 2004
Advisory ID: IMNX-2004-73-002-01
Author: Seth Arnold <sarnold@...unix.com>
-----------------------------------------------------------------------
Description:
Greg MacManus, of iDEFENSE Labs, reports finding several potentially
exploitable buffer overflows in XFree86's font code. David Dawes
provided a patch to fix these, and other, errors. Thanks also to
Patrick Volkerding for working with the patch, to allow it to more
easily apply to our version of XFree86.
As the overflowed buffers are auto variables and the functions
manipulating the buffers are string operations, StackGuard will prevent
successful exploitation of this vulnerability to gain new privileges;
however, StackGuard will kill any process that attempts to execute
exploit code. We recommend all our users upgrade to fixed packages,
which will prevent this denial of service attack.
