SuSE 11.3 Security Update : Linux Kernel (SAT Patch Numbers 9233 / 9236 / 9237)

High Nessus Plugin ID 74033

Synopsis

The remote SuSE 11 host is missing one or more security updates.

Description

The SUSE Linux Enterprise 11 Service Pack 3 kernel was updated to fix the following severe security issues :

 - 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-2014-1737)

 - 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-2014-1738)

 - 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. (bnc#875690).
 (CVE-2014-0196)

Solution

Apply SAT patch number 9233 / 9236 / 9237 as appropriate.
