SUSE SLES12 Security Update : kernel (SUSE-SU-2018:1227-1)

Medium Nessus Plugin ID 109763

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for the Linux Kernel 3.12.74-60_64_82 fixes several issues. The following security issues were fixed :

- CVE-2018-1000199: A bug in x86 debug register handling of ptrace() could lead to memory corruption, possibly a denial of service or privilege escalation (bsc#1090036).

- CVE-2017-0861: Use-after-free vulnerability in the snd_pcm_info function in the ALSA subsystem in the Linux kernel allowed attackers to gain privileges via unspecified vectors (bsc#1088268).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or 'zypper patch'.
