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).
