CVE-2012-4542 Open this link in a new tabHow to fix?
Upgrade Oracle:5 kernel-uek-debug to version 0:2.6.32-400.29.1.el5uek or higher.
This issue was patched in ELSA-2013-2534.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug package and not the kernel-uek-debug package as distributed by Oracle.
See How to fix? for Oracle:5 relevant fixed versions and status.
block/scsi_ioctl.c in the Linux kernel through 3.8 does not properly consider the SCSI device class during authorization of SCSI commands, which allows local users to bypass intended access restrictions via an SG_IO ioctl call that leverages overlapping opcodes.
