SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2016:0585-1)

High Nessus Plugin ID 89022

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.53 to receive various security and bugfixes.

The following security bugs were fixed :

- CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel allowed local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls (bnc#955654).

- CVE-2015-5707: Integer overflow in the sg_start_req function in drivers/scsi/sg.c in the Linux kernel allowed local users to cause a denial of service or possibly have unspecified other impact via a large iov_count value in a write request (bnc#940338).

- CVE-2015-7550: The keyctl_read_key function in security/keys/keyctl.c in the Linux kernel did not properly use a semaphore, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted application that leverages a race condition between keyctl_revoke and keyctl_read calls (bnc#958951).

- CVE-2015-7799: The slhc_init function in drivers/net/slip/slhc.c in the Linux kernel did not ensure that certain slot numbers are valid, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) via a crafted PPPIOCSMAXCID ioctl call (bnc#949936).

- CVE-2015-8215: net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel did not validate attempted changes to the MTU value, which allowed context-dependent attackers to cause a denial of service (packet loss) via a value that was (1) smaller than the minimum compliant value or (2) larger than the MTU of an interface, as demonstrated by a Router Advertisement (RA) message that is not validated by a daemon, a different vulnerability than CVE-2015-0272 (bnc#955354).

- CVE-2015-8539: The KEYS subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (BUG) via crafted keyctl commands that negatively instantiate a key, related to security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and security/keys/user_defined.c (bnc#958463).

- 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-2015-8550: Optimizations introduced by the compiler could have lead to double fetch vulnerabilities, potentially possibly leading to arbitrary code execution in backend (bsc#957988).

- CVE-2015-8551: Xen PCI backend driver did not perform proper sanity checks on the device's state, allowing for DoS (bsc#957990).

- 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-2015-8575: The sco_sock_bind function in net/bluetooth/sco.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#959399).

- CVE-2015-8660: The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel attempted to merge distinct setattr operations, which allowed local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application (bnc#960281).

- CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux kernel did not properly manage the relationship between a lock and a socket, which allowed local users to cause a denial of service (deadlock) via a crafted sctp_accept call (bnc#961509).

- CVE-2015-8785: The fuse_fill_write_pages function in fs/fuse/file.c in the Linux kernel allowed local users to cause a denial of service (infinite loop) via a writev system call that triggers a zero length for the first segment of an iov (bnc#963765).

- CVE-2016-0723: Race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel allowed local users to obtain sensitive information from kernel memory or cause a denial of service (use-after-free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call (bnc#961500).

- CVE-2016-2069: A race in invalidating paging structures that were not in use locally could have lead to disclosoure of information or arbitrary code exectution (bnc#963767).

The update package also includes non-security fixes. See advisory for details.

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.
