Affected Products:

openSUSE Leap 42.1

______________________________________________________________________________

 

An update that solves 10 vulnerabilities and has 18 fixes

is now available.

 

Description:

 

 

The Linux kernel for openSUSE Leap 42.1 was updated to the 4.1.15 stable

release, and also includes security and bugfixes.

 

Following security bugs were fixed:

- CVE-2016-0728: A reference leak in keyring handling with

join_session_keyring() could lead to local attackers gain root

privileges. (bsc#962075).

- CVE-2015-7550: A local user could have triggered a race between read and

revoke in keyctl (bnc#958951).

- CVE-2015-8767: A case can occur when sctp_accept() is called by the user

during a heartbeat timeout event after the 4-way handshake. Since

sctp_assoc_migrate() changes both assoc->base.sk and assoc->ep, the

bh_sock_lock in sctp_generate_heartbeat_event() will be taken with the

listening socket but released with the new association socket. The

result is a deadlock on any future attempts to take the listening socket

lock. (bsc#961509)

- CVE-2015-8539: A negatively instantiated user key could have been used

by a local user to leverage privileges (bnc#958463).

- CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions in

drivers/net/ppp/pptp.c in the Linux kernel did not verify an address

length, which allowed local users to obtain sensitive information from

kernel memory and bypass the KASLR protection mechanism via a crafted

application (bnc#959190).

- CVE-2015-8543: The networking implementation in the Linux kernel did not

validate protocol identifiers for certain protocol families, which

allowed local users to cause a denial of service (NULL function pointer

dereference and system crash) or possibly gain privileges by leveraging

CLONE_NEWUSER support to execute a crafted SOCK_RAW application

(bnc#958886).

- CVE-2015-8575: Validate socket address length in sco_sock_bind() to

prevent information leak (bsc#959399).

- CVE-2015-8551, CVE-2015-8552: xen/pciback: For

XEN_PCI_OP_disable_msi[|x] only disable if device has MSI(X) enabled

(bsc#957990).

- CVE-2015-8550: Compiler optimizations in the XEN PV backend drivers

could have lead to double fetch vulnerabilities, causing denial of

service or arbitrary code execution (depending on the configuration)

(bsc#957988).
