CVE-2011-1012

Status Candidate

Overview

The ldm_parse_vmdb function in fs/partitions/ldm.c in the Linux kernel before 2.6.38-rc6-git6 does not validate the VBLK size value in the VMDB structure in an LDM partition table, which allows local users to cause a denial of service (divide-by-zero error and OOPS) via a crafted partition table.

Ubuntu Security Notice 1204-1 - Dan Rosenberg discovered that the Linux kernel TIPC implementation contained multiple integer signedness errors. A local attacker could exploit this to gain root privileges. Dan Rosenberg discovered that multiple terminal ioctls did not correctly initialize structure memory. A local attacker could exploit this to read portions of kernel stack memory, leading to a loss of privacy. Various other issues were also addressed.

Ubuntu Security Notice 1160-1 - Dan Rosenberg discovered that IRDA did not correctly check the size of buffers. On non-x86 systems, a local attacker could exploit this to read kernel heap memory, leading to a loss of privacy. Dan Rosenburg discovered that the CAN subsystem leaked kernel addresses into the /proc filesystem. A local attacker could use this to increase the chances of a successful memory corruption exploit. Kees Cook discovered that the IOWarrior USB device driver did not correctly check certain size fields. A local attacker with physical access could plug in a specially crafted USB device to crash the system or potentially gain root privileges. Various other issues were also addressed.

Ubuntu Security Notice 1146-1 - Kees Cook discovered that some ethtool functions did not correctly clear heap memory. A local attacker with CAP_NET_ADMIN privileges could exploit this to read portions of kernel heap memory, leading to a loss of privacy. Kees Cook discovered that the IOWarrior USB device driver did not correctly check certain size fields. A local attacker with physical access could plug in a specially crafted USB device to crash the system or potentially gain root privileges. Various other issues were also addressed.

Ubuntu Security Notice 1141-1 - Brad Spengler discovered that the kernel did not correctly account for userspace memory allocations during exec() calls. A local attacker could exploit this to consume all system memory, leading to a denial of service. Alexander Duyck discovered that the Intel Gigabit Ethernet driver did not correctly handle certain configurations. If such a device was configured without VLANs, a remote attacker could crash the system, leading to a denial of service. Various other issues were also discovered.
