Please Install the Updated Packages.

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-&gt 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-&gt 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 &quot quota=on&quot or &quot quota=account&quot 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 ( ... Description truncated, for more information please check the Reference URL
