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).
