SUSE SLED11 / SLES11 Security Update : kernel (SUSE-SU-2015:1174-1)

medium Nessus Plugin ID 84545

Synopsis

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

Description

The SUSE Linux Enterprise 11 Service Pack 3 kernel was updated to fix various bugs and security issues.

The following vulnerabilities have been fixed :

CVE-2015-3636: A missing sk_nulls_node_init() in ping_unhash() inside the ipv4 stack can cause crashes if a disconnect is followed by another connect() attempt. (bnc#929525)

CVE-2015-3339: Race condition in the prepare_binprm function in fs/exec.c in the Linux kernel before 3.19.6 allows local users to gain privileges by executing a setuid program at a time instant when a chown to root is in progress, and the ownership is changed but the setuid bit is not yet stripped. (bnc#928130)

CVE-2015-3331: The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before 3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an AF_ALG(aead) socket. (bnc#927257)

CVE-2015-2922: The ndisc_router_discovery function in net/ipv6/ndisc.c in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack in the Linux kernel before 3.19.6 allows remote attackers to reconfigure a hop-limit setting via a small hop_limit value in a Router Advertisement (RA) message. (bnc#922583)

CVE-2015-2830: arch/x86/kernel/entry_64.S in the Linux kernel before 3.19.2 does not prevent the TS_COMPAT flag from reaching a user-mode task, which might allow local users to bypass the seccomp or audit protection mechanism via a crafted application that uses the (1) fork or (2) close system call, as demonstrated by an attack against seccomp before 3.16. (bnc#926240)

CVE-2015-2150: XSA-120: Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command registers, which might allow local guest users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response.
(bnc#919463)

CVE-2015-2042: net/rds/sysctl.c in the Linux kernel before 3.19 uses an incorrect data type in a sysctl table, which allows local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry.
(bnc#919018)

CVE-2015-2041: net/llc/sysctl_net_llc.c in the Linux kernel before 3.19 uses an incorrect data type in a sysctl table, which allows local users to obtain potentially sensitive information from kernel memory or possibly have unspecified other impact by accessing a sysctl entry.
(bnc#919007)

CVE-2015-1421: Use-after-free vulnerability in the sctp_assoc_update function in net/sctp/associola.c in the Linux kernel before 3.18.8 allows remote attackers to cause a denial of service (slab corruption and panic) or possibly have unspecified other impact by triggering an INIT collision that leads to improper handling of shared-key data.
(bnc#915577)

CVE-2015-0777: drivers/xen/usbback/usbback.c in 1 -2.6.18-xen-3.4.0 (aka the Xen 3.4.x support patches for the Linux kernel 2.6.18), as used in the Linux kernel 2.6.x and 3.x in SUSE Linux distributions, allows guest OS users to obtain sensitive information from uninitialized locations in host OS kernel memory via unspecified vectors. (bnc#917830)

CVE-2014-9683: Off-by-one error in the ecryptfs_decode_from_filename function in fs/ecryptfs/crypto.c in the eCryptfs subsystem in the Linux kernel before 3.18.2 allows local users to cause a denial of service (buffer overflow and system crash) or possibly gain privileges via a crafted filename. (bnc#918333)

CVE-2014-9529: Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 3.18.2 allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key. (bnc#912202)

CVE-2014-9419: The __switch_to function in arch/x86/kernel/process_64.c in the Linux kernel through 3.18.1 does not ensure that Thread Local Storage (TLS) descriptors are loaded before proceeding with other steps, which makes it easier for local users to bypass the ASLR protection mechanism via a crafted application that reads a TLS base address. (bnc#911326)

CVE-2014-8159: The InfiniBand (IB) implementation in the Linux kernel does not properly restrict use of User Verbs for registration of memory regions, which allows local users to access arbitrary physical memory locations, and consequently cause a denial of service (system crash) or gain privileges, by leveraging permissions on a uverbs device under /dev/infiniband/. (bnc#914742)

CVE-2014-8086: Race condition in the ext4_file_write_iter function in fs/ext4/file.c in the Linux kernel through 3.17 allows local users to cause a denial of service (file unavailability) via a combination of a write action and an F_SETFL fcntl operation for the O_DIRECT flag.
(bnc#900881)
