Description Mark J. Cox 2006-01-06 16:48:44 UTC
+++ This bug was initially created as a clone of Bug #177136 +++

CVE-2006-0095 says:
        dm-crypt in Linux kernel 2.6.15 and earlier does not clear a
        structure before it is freed, which leads to a memory
        disclosure that could allow local users to obtain sensitive
        information about a cryptographic key.

More details and the straightforward patch are here:

Comment 1 Dave Jones 2006-02-03 05:47:04 UTC
This is a mass-update to all currently open kernel bugs.

A new kernel update has been released (Version: 2.6.15-1.1830_FC4)
based upon a new upstream kernel release.

Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.

This bug has been placed in NEEDINFO_REPORTER state.
Due to the large volume of inactive bugs in bugzilla, if this bug is
still in this state in two weeks time, it will be closed.

Should this bug still be relevant after this period, the reporter
can reopen the bug at any time. Any other users on the Cc: list
of this bug can request that the bug be reopened by adding a
comment to the bug.

If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.

Thank you.


Comment 2 Mark J. Cox 2006-02-03 08:22:03 UTC
not fixed in 2.6.15 or by backported patch

Comment 3 Dave Jones 2006-02-03 19:10:00 UTC
ok, fixed in cvs, and pushed to upstream -stable maintainers.
I erroneously thought that this was covered in 2.6.15.2
