A vulnerability has been discovered in the Linux kernel that may lead to privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problem: CVE-2009-2692 Tavis Ormandy and Julien Tinnes discovered an issue with how the sendpage function is initialized in the proto_ops structure. Local users can exploit this vulnerability to gain elevated privileges. For the ol ...

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: CVE-2009-4307 Nageswara R Sastry reported an issue in the ext4 filesystem. Local users with the privileges to mount a filesystem can cause a denial of service by providing a s_log_groups_p ...

It was discovered that the Linux kernel did not correctly handle memory protection of the Virtual Dynamic Shared Object page when running a 32-bit application on a 64-bit kernel. A local attacker could exploit this to cause a denial of service. It was discovered that the r8169 network driver did not correctly check the size of Ethernet frames. A remote attacker could send specially crafted traff ...

Mathias Krause discovered that the Linux kernel did not correctly handle missing ELF interpreters. A local attacker could exploit this to cause the system to crash, leading to a denial of service. Marcelo Tosatti discovered that the Linux kernel"s hardware virtualization did not correctly handle reading the /dev/port special device. A local attacker in a guest operating system could issue a speci ...

Hugo Dias discovered that the ATM subsystem did not correctly manage socket counts. A local attacker could exploit this to cause a system hang, leading to a denial of service. It was discovered that the inotify subsystem contained watch removal race conditions. A local attacker could exploit this to crash the system, leading to a denial of service. Dann Frazier discovered that in certain situati ...

Tavis Ormandy and Julien Tinnes discovered that Linux did not correctly initialize certain socket operation function pointers. A local attacker could exploit this to gain root privileges. By default, Ubuntu 8.04 and later with a non-zero /proc/sys/vm/mmap_min_addr setting were not vulnerable.

It was discovered that the AX.25 network subsystem did not correctly check integer signedness in certain setsockopt calls. A local attacker could exploit this to crash the system, leading to a denial of service. Ubuntu 9.10 was not affected. Jan Beulich discovered that the kernel could leak register contents to 32-bit processes that were switched to 64-bit mode. A local attacker could run a speci ...

David Ford discovered that the IPv4 defragmentation routine did not correctly handle oversized packets. A remote attacker could send specially crafted traffic that would cause a system to crash, leading to a denial of service. Akira Fujita discovered that the Ext4 "move extents" ioctl did not correctly check permissions. A local attacker could exploit this to overwrite arbitrary files ...

Hugo Dias discovered that the ATM subsystem did not correctly manage socket counts. A local attacker could exploit this to cause a system hang, leading to a denial of service. It was discovered that the libertas wireless driver did not correctly handle beacon and probe responses. A physically near-by attacker could generate specially crafted wireless network traffic and cause a denial of service. ...
