SUSE SLES12 Security Update : kernel (SUSE-SU-2016:3119-1)
Critical Nessus Plugin ID 95805
SynopsisThe remote SUSE host is missing one or more security updates.
DescriptionThis update for the Linux Kernel 3.12.51-52_39 fixes several issues.
The following security bugs were fixed :
- CVE-2016-8655: A race condition in the af_packet packet_set_ring function could be used by local attackers to crash the kernel or gain privileges (bsc#1012759).
- CVE-2016-9555: The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel lacks chunk-length checking for the first chunk, which allowed remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data (bsc#1012183).
- CVE-2016-7117: Use-after-free vulnerability in the
__sys_recvmmsg function in net/socket.c in the Linux kernel allowed remote attackers to execute arbitrary code via vectors involving a recvmmsg system call that is mishandled during error processing (bsc#1003253).
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.
