CVE-2010-4243

Status Candidate

Overview

fs/exec.c in the Linux kernel before 2.6.37 does not enable the OOM Killer to assess use of stack memory by arrays representing the (1) arguments and (2) environment, which allows local users to cause a denial of service (memory consumption) via a crafted exec system call, aka an "OOM dodging issue," a related issue to CVE-2010-3858.

Ubuntu Security Notice USN-1204-1
Posted Sep 14, 2011
Authored by Ubuntu | Site security.ubuntu.com

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 1159-1 - 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 addressed.
