Ubuntu 10.04 LTS : linux, linux-ec2 vulnerabilities (USN-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. CVE-2010-4243 Alexander Duyck discovered that the Intel Gigabit Ethernet driver...

kernel: proc: protect mm start_code/end_code in /proc/pid/stat

The dotaskstat function in fs/proc/array.c in the Linux kernel before 2.6.39-rc1 does not perform an expected uid check, which makes it easier for local users to defeat the ASLR protection mechanism by reading the startcode and endcode fields in the /proc//stat file for a process executing a PIE...
