CAN-2005-1265 Prevent NULL mmap in topdown model
Last modified: 2007-11-30 17:07:18 EST
Chris wright reported a problem with the topdown allocator. This issue is
believed to allow a crash, but not result in gaining privileges (most likely due
to the BUG() cases added to 2.6 after a previous exploit).
We didn't check RHEL4 specifically to determine if this issue affect our shipped
version. More details see
I just submitted a patch.
