Ifyou use linux-restricted-modules, you have to update that package aswell to get modules which work with the new kernel version. Unless youmanually uninstalled the standard kernel metapackages (e.g. linux-generic,linux-server, linux-powerpc), a standard system upgrade will automaticallyperform this as well.Details follow:It was discovered that the Xen hypervisor block driver did not correctlyvalidate requests. A user with root privileges in a guest OS could make amalicious IO request with a large number of blocks that would crash thehost OS, leading to a denial of service. This only affected Ubuntu 7.10.(CVE-2007-5498)It was discovered the the i915 video driver did not correctly validatememory addresses. A local attacker could exploit this to remap memory thatcould cause a system crash, leading to a denial of service. This issue didnot affect Ubuntu 6.06 and was previous fixed for Ubuntu 7.10 and 8.04 inUSN-659-1. Ubuntu 8.10 has now been corrected as well. (CVE-2008-3831)David Watson discovered that the kernel did not correctly strip permissionswhen creating files in setgid directories. A local user could exploit thisto gain additional group privileges. This issue only affected Ubuntu 6.06.(CVE-2008-4210)Olaf Kirch and Miklos Szeredi discovered that the Linux kernel didnot correctly reject the append flag when handling file splicerequests. A local attacker could bypass append mode and make changes toarbitrary locations in a file. This issue only affected Ubuntu 7.10 and8.04. (CVE-2008-4554)It was discovered that the SCTP stack did not correctly handle INIT-ACK. Aremote user could exploit this by sending specially crafted SCTP trafficwhich would trigger a crash in the system, leading to a denial of service.This issue did not affect Ubuntu 8.10. (CVE-2008-4576)It was discovered that the SCTP stack did not correctly handle bad packetlengths. A remote user could exploit this by sending specially crafted SCTPtraffic which would trigger a crash in the system, leading to a denial ofservice. This issue did not affect Ubuntu 8.10. (CVE-2008-4618)Eric Sesterhenn discovered multiple flaws in the HFS+ filesystem. If alocal user or automated system were tricked into mounting a malicious HFS+filesystem, the system could crash, leading to a denial of service.(CVE-2008-4933, CVE-2008-4934, CVE-2008-5025)It was discovered that the Unix Socket handler did not correctly processthe SCM_RIGHTS message. A local attacker could make a malicious socketrequest that would crash the system, leading to a denial of service.(CVE-2008-5029)It was discovered that the driver for simple i2c audio interfaces did notcorrectly validate certain function pointers.
