----------------------------------------------------------------------- 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@xxxxxxxxxxx> ----------------------------------------------------------------------- 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.
