SUSE Security Update: Security update for Linux kernel ______________________________________________________________________________ Announcement ID: SUSE-SU-2014:0683-1 Rating: important References: #875690 #875798 Cross-References: CVE-2014-0196 CVE-2014-1737 CVE-2014-1738 Affected Products: SUSE Linux Enterprise Real Time Extension 11 SP3 ______________________________________________________________________________ An update that fixes three vulnerabilities is now available. It includes one version update. Description: The SUSE Linux Enterprise 11 Service Pack 3 RealTime Extension kernel has been updated to fix two critical security issues. The following security bugs have been fixed: * CVE-2014-1737: The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations and gain privileges by leveraging write access to a /dev/fd device. (bnc#875798) * CVE-2014-1738: The raw_cmd_copyout function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly restrict access to certain pointers during processing of an FDRAWCMD ioctl call, which allows local users to obtain sensitive information from kernel heap memory by leveraging write access to a /dev/fd device. (bnc#875798) * CVE-2014-0196: The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST" case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings.
