Red Hat Bugzilla – Bug 138534
CVE-2004-1056 insufficient locking checks in DRM code
Last modified: 2007-11-30 17:07:05 EST
Stefan Dirsch reported to the freedesktop.org bugzilla an issue with
permissions within the DRM code.
See this url for more information, including a patch.
This issue should also affect RHEL2.1
This issue probably also affects RHEL4.
DRM source is part of both the kernel and X. We build it in the
kernel. Reassigning to kernel component.
Peter/Tim, I'm assuming that DaveJ is too busy with RHEL4 to take on
this bug. But I don't know who else covers this area. I'm sticking
PeterM with this for now (presumably for appropriate reassignment).
Josh, the URL in your initial comment times out. Could you please
provide another pointer? Thanks in advance.
freedesktop.org seems to be down. I don't have a different source for
this information, hopefully the site comes back alive soon. If not
I'll do some digging.
Freedesktop.org was compromised. Google has it in cache:
