Linux kernel vulnerabilities

Description

## Releases * Ubuntu 8.04 * Ubuntu 7.10 * Ubuntu 6.06 ## Packages * linux \- * linux-source-2.6.15 \- * linux-source-2.6.22 \- It was discovered that the direct-IO subsystem did not correctly validate certain structures. A local attacker could exploit this to cause a system crash, leading to a denial of service. (CVE-2007-6716) It was discovered that the disabling of the ZERO_PAGE optimization could lead to large memory consumption. A local attacker could exploit this to allocate all available memory, leading to a denial of service. (CVE-2008-2372) It was discovered that the Datagram Congestion Control Protocol (DCCP) did not correctly validate its arguments. If DCCP was in use, a remote attacker could send specially crafted network traffic and cause a system crash, leading to a denial of service. (CVE-2008-3276) It was discovered that the SBNI WAN driver did not correctly check for the NET_ADMIN capability. A malicious local root user lacking CAP_NET_ADMIN would be able to change the WAN device configuration, leading to a denial of service. (CVE-2008-3525) It was discovered that the Stream Control Transmission Protocol (SCTP) did not correctly validate the key length in the SCTP_AUTH_KEY option. If SCTP is in use, a remote attacker could send specially crafted network traffic that would crash the system, leading to a denial of service. (CVE-2008-3526) It was discovered that the tmpfs implementation did not correctly handle certain sequences of inode operations. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2008-3534) It was discovered that the readv/writev functions did not correctly handle certain sequences of file operations. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2008-3535) It was discovered that SCTP did not correctly validate its userspace arguments. A local attacker could call certain sctp_* functions with malicious options and cause a system crash, leading to a denial of service. (CVE-2008-3792, CVE-2008-4113, CVE-2008-4445) 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. (CVE-2008-3831) Johann Dahm and David Richter discovered that NFSv4 did not correctly handle certain file ACLs. If NFSv4 is in use, a local attacker could create a malicious ACL that could cause a system crash, leading to a denial of service. (CVE-2008-3915)
