Description

## Releases * Ubuntu 8.10 * Ubuntu 8.04 * Ubuntu 7.10 * Ubuntu 6.06 ## Packages * linux \- * linux-backports-modules-2.6.15 \- * linux-backports-modules-2.6.22 \- * linux-backports-modules-2.6.24 \- * linux-backports-modules-2.6.27 \- * linux-restricted-modules \- * linux-restricted-modules-2.6.15 \- * linux-restricted-modules-2.6.22 \- * linux-restricted-modules-2.6.24 \- * linux-source-2.6.15 \- * linux-source-2.6.22 \- * linux-ubuntu-modules-2.6.22 \- * linux-ubuntu-modules-2.6.24 \- 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)
