ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well. Details follow: It was discovered that the Xen hypervisor block driver did not correctly validate requests. A user with root privileges in a guest OS could make a malicious IO request with a large number of blocks that would crash the host 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 validate memory addresses. A local attacker could exploit this to remap memory that could cause a system crash, leading to a denial of service. This issue did not affect Ubuntu 6.06 and was previous fixed for Ubuntu 7.10 and 8.04 in USN-659-1. Ubuntu 8.10 has now been corrected as well. (CVE-2008-3831) David Watson discovered that the kernel did not correctly strip permissions when creating files in setgid directories. A local user could exploit this to gain additional group privileges. This issue only affected Ubuntu 6.06. (CVE-2008-4210) Olaf Kirch and Miklos Szeredi discovered that the Linux kernel did not correctly reject the "append" flag when handling file splice requests. A local attacker could bypass append mode and make changes to arbitrary locations in a file. This issue only affected Ubuntu 7.10 and 8.04. (CVE-2008-4554) It was discovered that the SCTP stack did not correctly handle INIT-ACK. A remote user could exploit this by sending specially crafted SCTP traffic which 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 packet lengths. A remote user could exploit this by sending specially crafted SCTP traffic which would trigger a crash in the system, leading to a denial of service. This issue did not affect Ubuntu 8.10. (CVE-2008-4618) Eric Sesterhenn discovered multiple flaws in the HFS+ filesystem. If a local 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 process the SCM_RIGHTS message. A local attacker could make a malicious socket request 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 not correctly validate certain function pointers. A local user could exploit this to gain root privileges or crash the system, leading to a denial of service. (CVE-2008-5033)

=========================================================== Ubuntu Security Notice USN-680-1 November 27, 2008 samba vulnerability CVE-2008-4314 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 8.10 This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 8.10: samba 2:3.2.3-1ubuntu3.3 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: It was discovered that Samba did not properly perform bounds checking in certain operations. A remote attacker could possibly exploit this to read arbitrary memory contents of the smb process, which could contain sensitive infomation or possibly have other impacts, such as a denial of service.

=========================================================== Ubuntu Security Notice USN-678-1 November 26, 2008 gnutls12, gnutls13, gnutls26 vulnerability CVE-2008-4989 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 6.06 LTS Ubuntu 7.10 Ubuntu 8.04 LTS Ubuntu 8.10 This advisory also applies to the corresponding versions of Kubuntu, Edubuntu, and Xubuntu. The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: libgnutls12 1.2.9-2ubuntu1.3 Ubuntu 7.10: libgnutls13 1.6.3-1ubuntu0.2 Ubuntu 8.04 LTS: libgnutls13 2.0.4-1ubuntu2.2 Ubuntu 8.10: libgnutls26 2.4.1-1ubuntu0.1 In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Martin von Gagern discovered that GnuTLS did not properly verify certificate chains when the last certificate in the chain was self-signed. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could be exploited to view sensitive information. (CVE-2008-4989)
