Summary

extensions/libxt_tcp.c in iptables through 1.4.21 does not match TCP SYN+FIN packets in --syn rules, which might allow remote attackers to bypass intended firewall restrictions via crafted packets. NOTE: the CVE-2012-6638 fix makes this issue less relevant.

    descriptionThe SUSE Linux Enterprise 11 SP1 kernel have been updated to fix various bugs and security issues. The following security issues have been fixed : - Several buffer overread and overwrite errors in the UDF logical volume descriptor code were fixed that might have allowed local attackers able to mount UDF volumes to crash the kernel or potentially gain privileges. (CVE-2012-3400) - A local denial of service in the last epoll fix was fixed. (CVE-2012-3375) - A integer overflow in i915_gem_do_execbuffer() was fixed that might be used by local attackers to crash the kernel or potentially execute code. (CVE-2012-2384) - A integer overflow in i915_gem_execbuffer2() was fixed that might be used by local attackers to crash the kernel or potentially execute code. (CVE-2012-2383) - Memiory leaks in the hugetlbfs map reservation code were fixed that could be used by local attackers to exhaust machine memory.

  • NASL familySuSE Local Security Checks
    NASL idSUSE_KERNEL-8325.NASL
    descriptionThis Linux kernel update fixes various security issues and bugs in the SUSE Linux Enterprise 10 SP4 kernel. The following security issues have been fixed : - kernel/taskstats.c in the Linux kernel allowed local users to obtain sensitive I/O statistics by sending taskstats commands to a netlink socket, as demonstrated by discovering the length of another users password (a side channel attack). (CVE-2011-2494) - net/ipv6/netfilter/nf_conntrack_reasm.c in the Linux kernel, when the nf_conntrack_ipv6 module is enabled, allowed remote attackers to cause a denial of service (NULL pointer dereference and system crash) via certain types of fragmented IPv6 packets. (CVE-2012-2744) - Use-after-free vulnerability in the xacct_add_tsk function in kernel/tsacct.c in the Linux kernel allowed local users to obtain potentially sensitive information from kernel memory or cause a denial of service (system crash) via a taskstats TASKSTATS_CMD_ATTR_PID command. (CVE-2012-3510) - The user_update function in security/keys/user_defined.c in the Linux kernel 2.6 allowed local users to cause a denial of service (NULL pointer dereference and kernel oops) via vectors related to a user-defined key and updating a negative key into a fully instantiated key. (CVE-2011-4110) - The ib_uverbs_poll_cq function in drivers/infiniband/core/uverbs_cmd.c in the Linux kernel did not initialize a certain response buffer, which allowed local users to obtain potentially sensitive information from kernel memory via vectors that cause this buffer to be only partially filled, a different vulnerability than CVE-2010-4649. (CVE-2011-1044) - Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel allowed remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem. (CVE-2012-3400) - The sock_alloc_send_pskb function in net/core/sock.c in the Linux kernel did not properly validate a certain length value, which allowed local users to cause a denial of service (heap-based buffer overflow and system crash) or possibly gain privileges by leveraging access to a TUN/TAP device. (CVE-2012-2136) - A small denial of service leak in dropping syn+fin messages was fixed. (CVE-2012-2663) The following non-security issues have been fixed : Packaging : - kbuild: Fix gcc -x syntax (bnc#773831). NFS : - knfsd: An assortment of little fixes to the sunrpc cache code.
