(CVE-2007-6282)

(CVE-2008-1615)

The copy_to_user routine in the kernel did not correctly clear memory destination addresses when running on 64bit kernels. A local attacker could exploit this to gain access to sensitive kernel memory, leading to a loss of privacy. (CVE-2008-2729)

The PPP over L2TP routines in the kernel did not correctly handle certain messages. A remote attacker could send a specially crafted packet that could crash the system or execute arbitrary code.
(CVE-2008-2750)

Gabriel Campana discovered that SCTP routines did not correctly check for large addresses. A local user could exploit this to allocate all available memory, leading to a denial of service. (CVE-2008-2826).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel :

Memory leak in the ipip6_rcv function in net/ipv6/sit.c in the Linux kernel before 2.6.25.3 allows remote attackers to cause a denial of service (memory consumption) via network traffic to a Simple Internet Transition (SIT) tunnel interface, related to the pskb_may_pull and kfree_skb functions, and management of an skb reference count.
(CVE-2008-2136)

The utimensat system call (sys_utimensat) in Linux kernel 2.6.22 and other versions before 2.6.25.3 does not check file permissions when certain UTIME_NOW and UTIME_OMIT combinations are used, which allows local users to modify file times of arbitrary files, possibly leading to a denial of service. (CVE-2008-2148)

Integer overflow in the dccp_feat_change function in net/dccp/feat.c in the Datagram Congestion Control Protocol (DCCP) subsystem in the Linux kernel 2.6.18, and 2.6.17 through 2.6.20, allows local users to gain privileges via an invalid feature length, which leads to a heap-based buffer overflow. (CVE-2008-2358)

The pppol2tp_recvmsg function in drivers/net/pppol2tp.c in the Linux kernel 2.6 before 2.6.26-rc6 allows remote attackers to cause a denial of service (kernel heap memory corruption and system crash) and possibly have unspecified other impact via a crafted PPPOL2TP packet that results in a large value for a certain length variable.
(CVE-2008-2750)

Linux kernel 2.6.18, and possibly other versions, when running on AMD64 architectures, allows local users to cause a denial of service (crash) via certain ptrace calls. (CVE-2008-1615)

Integer overflow in the sctp_getsockopt_local_addrs_old function in net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) functionality in the Linux kernel before 2.6.25.9 allows local users to cause a denial of service (resource consumption and system outage) via vectors involving a large addr_num field in an sctp_getaddrs_old data structure. (CVE-2008-2826)

Race condition in the directory notification subsystem (dnotify) in Linux kernel 2.6.x before 2.6.24.6, and 2.6.25 before 2.6.25.1, allows local users to cause a denial of service (OOPS) and possibly gain privileges via unspecified vectors. (CVE-2008-1375)

The bdx_ioctl_priv function in the tehuti driver (tehuti.c) in Linux kernel 2.6.x before 2.6.25.1 does not properly check certain information related to register size, which has unspecified impact and local attack vectors, probably related to reading or writing kernel memory. (CVE-2008-1675)

Linux kernel before 2.6.25.2 does not apply a certain protection mechanism for fcntl functionality, which allows local users to (1) execute code in parallel or (2) exploit a race condition to obtain re-ordered access to the descriptor table. (CVE-2008-1669)

Additionaly, a number of fixes has been included for the rtc driver, Arima W651DI audio chipset, unionfs, as well as Tomoyolinux has been updated to 1.6.3, UDF 2.50 support was added, and a few things more.
Check the package changelog for more details.

To update your kernel, please follow the directions located at :

This kernel update fixes the following security problems:
CVE-2008-2136: A problem in SIT IPv6 tunnel handling could be used by remote attackers to immediately crash the machine.

CVE-2008-1615: On x86_64 a denial of service attack could be used by local attackers to immediately panic / crash the machine.

CVE-2008-2148: The permission checking in sys_utimensat was incorrect and local attackers could change the filetimes of files they do not own to the current time.

CVE-2008-1669: Fixed a SMP ordering problem in fcntl_setlk could potentially allow local attackers to execute code by timing file locking.

CVE-2008-1375: Fixed a dnotify race condition, which could be used by local attackers to potentially execute code.

CVE-2007-6282: A remote attacker could crash the IPSec/IPv6 stack by sending a bad ESP packet. This requires the host to be able to receive such packets (default filtered by the firewall).

CVE-2008-1367: Clear the 'direction' flag before calling signal handlers. For specific not yet identified programs under specific timing conditions this could potentially have caused memory corruption or code execution.
