An update that fixes three vulnerabilities is now available.

 

Description:

 

 

 

The SUSE Linux Enterprise 12 SP2 kernel was updated to receive critical

security fixes.

 

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#1012754).

- CVE-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the

Linux kernel did not validate the relationship between the minimum

fragment length and the maximum packet size, which allowed local users

to gain privileges or cause a denial of service (heap-based buffer

overflow) by leveraging the CAP_NET_ADMIN capability (bnc#1008831).

- 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 (bnc#1011685).
