Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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)

(CVE-2010-1173)

The Transparent Inter-Process Communication (TIPC) functionality in Linux kernel 2.6.16-rc1 through 2.6.33, and possibly other versions, allows local users to cause a denial of service (kernel OOPS) by sending datagrams through AF_TIPC before entering network mode, which triggers a NULL pointer dereference. (CVE-2010-1187)

The sctp_process_unk_param function in net/sctp/sm_make_chunk.c in the Linux kernel 2.6.33.3 and earlier, when SCTP is enabled, allows remote attackers to cause a denial of service (system crash) via an SCTPChunkInit packet containing multiple invalid parameters that require a large amount of error data. (CVE-2010-1173)

fs/cifs/cifssmb.c in the CIFS implementation in the Linux kernel before 2.6.34-rc4 allows remote attackers to cause a denial of service (panic) via an SMB response packet with an invalid CountHigh value, as demonstrated by a response from an OS/2 server, related to the CIFSSMBWrite and CIFSSMBWrite2 functions. (CVE-2010-2248)

Buffer overflow in the ecryptfs_uid_hash macro in fs/ecryptfs/messaging.c in the eCryptfs subsystem in the Linux kernel before 2.6.35 might allow local users to gain privileges or cause a denial of service (system crash) via unspecified vectors.
(CVE-2010-2492)

The xfs_swapext function in fs/xfs/xfs_dfrag.c in the Linux kernel before 2.6.35 does not properly check the file descriptors passed to the SWAPEXT ioctl, which allows local users to leverage write access and obtain read access by swapping one file into another file.
(CVE-2010-2226)

The gfs2_dirent_find_space function in fs/gfs2/dir.c in the Linux kernel before 2.6.35 uses an incorrect size value in calculations associated with sentinel directory entries, which allows local users to cause a denial of service (NULL pointer dereference and panic) and possibly have unspecified other impact by renaming a file in a GFS2 filesystem, related to the gfs2_rename function in fs/gfs2/ops_inode.c. (CVE-2010-2798)

The do_anonymous_page function in mm/memory.c in the Linux kernel before 2.6.27.52, 2.6.32.x before 2.6.32.19, 2.6.34.x before 2.6.34.4, and 2.6.35.x before 2.6.35.2 does not properly separate the stack and the heap, which allows context-dependent attackers to execute arbitrary code by writing to the bottom page of a shared memory segment, as demonstrated by a memory-exhaustion attack against the X.Org X server.

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)
