Description Mark J. Cox 2005-11-24 10:40:43 UTC

Although this issue is said to only affect 2.6, RHEL3 contained changes to
CLONE_THREAD bia nptl backport so this needs looking at by a kernel expert to
determine if RHEL3 needs this fix.  These are the only details we currently have:

+++ This bug was initially created as a clone of Bug #174075 +++

The ptrace functionality (ptrace.c) in Linux kernel 2.6 before
        2.6.14.2, using CLONE_THREAD, does not use the thread group ID
        to check whether it is attaching to itself, which allows local
        users to cause a denial of service (crash).

Mark, I think that we should declare RHEL3 as not vulnerable to
CVE-2005-3783, possible switching the resolution of this bug to
NOTABUG.  The only problem that PeterS encountered is the one
described in bug 170261, which is CVE-2005-3107.

Let us know what you think.

Changing disposition to NOTABUG.
