SUSE SLES12 Security Update : kernel (SUSE-SU-2017:2448-1)

Critical Nessus Plugin ID 103214


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


This update for the Linux Kernel 3.12.74-60_64_57 fixes several issues. The following security bugs were fixed :

- 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#1038564, bsc#1042892).

- CVE-2017-8890: The inet_csk_clone_lock function in net/ipv4/inet_connection_sock.c in the Linux kernel allowed attackers to cause a denial of service (double free) or possibly have unspecified other impact by leveraging use of the accept system call (bsc#1038564).

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.
