Synopsis

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

Description

This update for the Linux Kernel 3.12.61-52_83 fixes several issues.
The following security bugs were fixed :

- CVE-2017-1000112: Prevent a race condition in net-packet code that could have been exploited by unprivileged users to gain root access (bsc#1052368).

- CVE-2017-7645: The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel allowed remote attackers to cause a denial of service (system crash) via a long RPC reply (bsc#1046191).

- CVE-2017-9242: The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel was too late in checking whether an overwrite of an skb data structure may occur, which allowed local users to cause a denial of service (system crash) via crafted system calls (bsc#1042892).

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.
