Synopsis

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

Description

This update the for Linux Kernel 3.12.61-52.69 fixes one issue. The following security bug was fixed :

- CVE-2017-5970: The ipv4_pktinfo_prepare function in net/ipv4/ip_sockglue.c in the Linux kernel allowed attackers to cause a denial of service (system crash) via (1) an application that made crafted system calls or possibly (2) IPv4 traffic with invalid IP options (bsc#1025013).

- CVE-2017-7308: The packet_set_ring function in net/packet/af_packet.c in the Linux kernel did not properly validate certain block-size data, which allowed local users to cause a denial of service (overflow) or possibly have unspecified other impact via crafted system calls (bsc#1030575, bsc#1031660).

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.
