http://git.kernel.org/cgit/linux/kernel/git/nab/target-pending.git/commit/?id=cea4dcfdad926a27a18e188720efe0f2c9403456                                                                       
iscsi-target: fix heap buffer overflow on error

If a key was larger than 64 bytes, as checked by iscsi_check_key(), the error response packet, generated by iscsi_add_notunderstood_response(), would still attempt to copy the entire key into the packet, overflowing the structure on the heap. Remote preauthentication kernel memory corruption was possible if a target was configured and listening on the network.

Comment 17 Marcus Meissner 2013-05-31 06:36:51 UTC

This problem was introduced with commit e48354ce (v3.1-rc1~41) and backported
to the SLES 11 Service Pack 2 codebase.

It does not exist in SUSE Linux Enterprise 11 SP1 and earlier versions.

SUSE Linux Enterprise 10 is also not affected.

Comment 18 Marcus Meissner 2013-05-31 07:58:09 UTC

FWIW I also checked the iscsitarget KMPs we offer (iscsitarget-kmp-FLAVOUR), they do not have the affected code.
