Description Mark J. Cox 2005-01-11 15:43:40 UTC

CAN-2004-1074 fixes a flaw allowing a malicious binary to crash a system.  It
was found that a similar flaw also affected 64-bit ELF support, therefore
affecting ia64 support.  

Fixed upstream in 2.6;

Comment 1 Jim Paradis 2005-01-13 21:27:39 UTC

It turns out that only Derry (AS2.1-ia64) is vulnerable to this.  Pensacola
(AS2.1-x86) is based on a different kernel rev that handles insert_vma_struct()
differently.  The same type of poisoned binary that causes Derry to crash exits
with an error on Pensacola.  I'm updating the "hardware" field of this report
accordingly.

A fix for this problem has also been committed to the RHEL2.1 U7
patch pool (in kernel version 2.4.18-e.53)
