Summary
Live patch for the Linux Kernel
Details

This update contains a kernel live patch for the 3.12.36-38 SUSE Linux Enterprise Server 12 Kernel, fixing following security issues.

  • CVE-2015-3339: A race condition in the prepare_binprm function in fs/exec.c in the Linux kernel allowed 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. (bsc#939263 bsc#939044)

  • CVE-2015-1465: The IPv4 implementation in the Linux kernel did not properly consider the length of the Read-Copy Update (RCU) grace period for redirecting lookups in the absence of caching, which allowed remote attackers to cause a denial of service (memory consumption or system crash) via a flood of packets. (bsc#939044 bsc#916225)

  • CVE-2015-3636: The pingunhash function in net/ipv4/ping.c in the Linux kernel did not initialize a certain list data structure during an unhash operation, which allowed local users to gain privileges or cause a denial of service (use-after-free and system crash) by leveraging the ability to make a SOCKDGRAM socket system call for the IPPROTOICMP or IPPROTOICMPV6 protocol, and then making a connect system call after a disconnect. (bsc#939277)

  • CVE-2015-5364/CVE-2015-5366: Two denial of service attacks via a flood of UDP packets with invalid checksums were fixed that could be used by remote attackers to delay execution. (bsc#939276)

  • CVE-2015-1805: The (1) piperead and (2) pipewrite implementations in fs/pipe.c in the Linux kernel did not properly consider the side effects of failed _copytouserinatomic and _copyfromuserinatomic calls, which allowed local users to cause a denial of service (system crash) or possibly gain privileges via a crafted application, aka an 'I/O vector array overrun.' (bsc#939270)

  • CVE-2015-4700: A BPF Jit optimization flaw could allow local users to panic the kernel. (bsc#939273)

  • CVE-2015-3331: The _driverrfc4106decrypt function in arch/x86/crypto/aesni-intelglue.c in the Linux kernel did not properly determine the memory locations used for encrypted data, which allowed 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. (bsc#939262)

  • CVE-2014-8159: The InfiniBand (IB) implementation in the Linux kernel did not properly restrict use of User Verbs for registration of memory regions, which allowed 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/. (bsc#939241)

  • CVE-2014-7822: The implementation of certain splice_write file operations in the Linux kernel before 3.16 does not enforce a restriction on the maximum size of a single file, which allows local users to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted splice system call, as demonstrated by use of a file descriptor associated with an ext4 filesystem. (bsc#939240)
