The openSUSE 11.0 kernel was updated to fix following security issues :

CVE-2009-4020: Stack-based buffer overflow in the hfs subsystem in the Linux kernel 2.6.32 allows remote attackers to have an unspecified impact via a crafted Hierarchical File System (HFS) filesystem, related to the hfs_readdir function in fs/hfs/dir.c.

CVE-2010-0307: The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 2.6.32.8 on the x86_64 platform does not ensure that the ELF interpreter is available before a call to the SET_PERSONALITY macro, which allows local users to cause a denial of service (system crash) via a 32-bit application that attempts to execute a 64-bit application and then triggers a segmentation fault, as demonstrated by amd64_killer, related to the flush_old_exec function.

CVE-2010-0622: The wake_futex_pi function in kernel/futex.c in the Linux kernel before 2.6.33-rc7 does not properly handle certain unlock operations for a Priority Inheritance (PI) futex, which allows local users to cause a denial of service (OOPS) and possibly have unspecified other impact via vectors involving modification of the futex value from user space.

CVE-2010-0410: drivers/connector/connector.c in the Linux kernel before 2.6.32.8 allows local users to cause a denial of service (memory consumption and system crash) by sending the kernel many NETLINK_CONNECTOR messages.

CVE-2010-0415: The do_pages_move function in mm/migrate.c in the Linux kernel before 2.6.33-rc7 does not validate node values, which allows local users to read arbitrary kernel memory locations, cause a denial of service (OOPS), and possibly have unspecified other impact by specifying a node that is not part of the kernel's node set.

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issues :

* multiple flaws were found in the mmap and mremap implementations. A local user could use these flaws to cause a local denial of service or escalate their privileges. (CVE-2010-0291, Important)

* a NULL pointer dereference flaw was found in the Fast Userspace Mutexes (futexes) implementation. The unlock code path did not check if the futex value associated with pi_state->owner had been modified.
A local user could use this flaw to modify the futex value, possibly leading to a denial of service or privilege escalation when the pi_state->owner pointer is dereferenced. (CVE-2010-0622, Important)

* a NULL pointer dereference flaw was found in the Linux kernel Network File System (NFS) implementation. A local user on a system that has an NFS-mounted file system could use this flaw to cause a denial of service or escalate their privileges on that system.
(CVE-2010-1087, Important)

* a flaw was found in the sctp_process_unk_param() function in the Linux kernel Stream Control Transmission Protocol (SCTP) implementation. A remote attacker could send a specially crafted SCTP packet to an SCTP listening port on a target system, causing a kernel panic (denial of service). (CVE-2010-1173, Important)

* a flaw was found in the Linux kernel Transparent Inter-Process Communication protocol (TIPC) implementation. If a client application, on a local system where the tipc module is not yet in network mode, attempted to send a message to a remote TIPC node, it would dereference a NULL pointer on the local system, causing a kernel panic (denial of service). (CVE-2010-1187, Important)

* a buffer overflow flaw was found in the Linux kernel Global File System 2 (GFS2) implementation. In certain cases, a quota could be written past the end of a memory page, causing memory corruption, leaving the quota stored on disk in an invalid state. A user with write access to a GFS2 file system could trigger this flaw to cause a kernel crash (denial of service) or escalate their privileges on the GFS2 server. This issue can only be triggered if the GFS2 file system is mounted with the 'quota=on' or 'quota=account' mount option.
(CVE-2010-1436, Important)

* a race condition between finding a keyring by name and destroying a freed keyring was found in the Linux kernel key management facility. A local user could use this flaw to cause a kernel panic (denial of service) or escalate their privileges. (CVE-2010-1437, Important)

* a flaw was found in the link_path_walk() function in the Linux kernel. Using the file descriptor returned by the open() function with the O_NOFOLLOW flag on a subordinate NFS-mounted file system, could result in a NULL pointer dereference, causing a denial of service or privilege escalation. (CVE-2010-1088, Moderate)

* a missing permission check was found in the gfs2_set_flags() function in the Linux kernel GFS2 implementation. A local user could use this flaw to change certain file attributes of files, on a GFS2 file system, that they do not own. (CVE-2010-1641, Low)
