ATTENTION: Due to an unavoidable ABI change (except for Ubuntu 6.06) 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: Amerigo Wang and Eric Sesterhenn discovered that the HFS and ext4 filesystems did not correctly check certain disk structures. If a user were tricked into mounting a specially crafted filesystem, a remote attacker could crash the system or gain root privileges. (CVE-2009-4020, CVE-2009-4308) It was discovered that FUSE did not correctly check certain requests. A local attacker with access to FUSE mounts could exploit this to crash the system or possibly gain root privileges. Ubuntu 9.10 was not affected. (CVE-2009-4021) It was discovered that KVM did not correctly decode certain guest instructions. A local attacker in a guest could exploit this to trigger high scheduling latency in the host, leading to a denial of service. Ubuntu 6.06 was not affected. (CVE-2009-4031) It was discovered that the OHCI fireware driver did not correctly handle certain ioctls. A local attacker could exploit this to crash the system, or possibly gain root privileges. Ubuntu 6.06 was not affected. (CVE-2009-4138) Tavis Ormandy discovered that the kernel did not correctly handle O_ASYNC on locked files. A local attacker could exploit this to gain root privileges. Only Ubuntu 9.04 and 9.10 were affected. (CVE-2009-4141) Neil Horman and Eugene Teo discovered that the e1000 and e1000e network drivers did not correctly check the size of Ethernet frames. An attacker on the local network could send specially crafted traffic to bypass packet filters, crash the system, or possibly gain root privileges. (CVE-2009-4536, CVE-2009-4538) It was discovered that "print-fatal-signals" reporting could show arbitrary kernel memory contents. A local attacker could exploit this, leading to a loss of privacy. By default this is disabled in Ubuntu and did not affect Ubuntu 6.06. (CVE-2010-0003) Olli Jarva and Tuomo Untinen discovered that IPv6 did not correctly handle jumbo frames. A remote attacker could exploit this to crash the system, leading to a denial of service. Only Ubuntu 9.04 and 9.10 were affected. (CVE-2010-0006) Florian Westphal discovered that bridging netfilter rules could be modified by unprivileged users. A local attacker could disrupt network traffic, leading to a denial of service. (CVE-2010-0007) Al Viro discovered that certain mremap operations could leak kernel memory. A local attacker could exploit this to consume all available memory, leading to a denial of service. (CVE-2010-0291)

Details follow: Ronald Volgers discovered that the mount.cifs utility, when installed as a setuid program, suffered from a race condition when verifying user permissions. A local attacker could trick samba into mounting over arbitrary locations, leading to a root privilege escalation.

USN-891-1: lintian vulnerabilities

Details follow: Raphael Geissert discovered that lintian did not correctly validate certain filenames when processing input. If a user or an automated system were tricked into running lintian on a specially crafted set of files, a remote attacker could execute arbitrary code with user privileges.

USN-803-2: Dhcp vulnerability

Referenced CVEs: 
CVE-2009-0692
Description: 
=========================================================== Ubuntu Security Notice USN-803-2 January 27, 2010 dhcp3 vulnerability CVE-2009-0692 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 8.10 Ubuntu 9.04 Ubuntu 9.10 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: dhcp3-client 3.1.1-1ubuntu2.2 dhcp3-client-udeb 3.1.1-1ubuntu2.2 Ubuntu 9.04: dhcp-client 3.1.1-5ubuntu8.2 dhcp3-client 3.1.1-5ubuntu8.2 Ubuntu 9.10: dhcp-client 3.1.2-1ubuntu7.1 dhcp3-client 3.1.2-1ubuntu7.1 After a standard system upgrade you need to restart any DHCP network connections utilizing dhclient3 to effect the necessary changes. Details follow: USN-803-1 fixed a vulnerability in Dhcp. Due to an error, the patch to fix the vulnerability was not properly applied on Ubuntu 8.10 and higher. Even with the patch improperly applied, the default compiler options reduced the vulnerability to a denial of service. Additionally, in Ubuntu 9.04 and higher, users were also protected by the AppArmor dhclient3 profile. This update fixes the problem. Original advisory details: It was discovered that the DHCP client as included in dhcp3 did not verify the length of certain option fields when processing a response from an IPv4 dhcp server. If a user running Ubuntu 6.06 LTS or 8.04 LTS connected to a malicious dhcp server, a remote attacker could cause a denial of service or execute arbitrary code as the user invoking the program, typically the 'dhcp' user. For users running Ubuntu 8.10 or 9.04, a remote attacker should only be able to cause a denial of service in the DHCP client. In Ubuntu 9.04, attackers would also be isolated by the AppArmor dhclient3 profile.

The problem can be corrected by upgrading your system to the following package versions: Ubuntu 6.06 LTS: python2.4-xml 0.8.4-1ubuntu3.1 After a standard system upgrade you need to restart any applications that use PyXML to effect the necessary changes. Details follow: USN-890-1 fixed vulnerabilities in Expat. This update provides the corresponding updates for PyXML. Original advisory details: Jukka Taimisto, Tero Rontti and Rauli Kaksonen discovered that Expat did not properly process malformed XML.
