CVE-2011-1593

Published: 3 May 2011

Multiple integer overflows in the next_pidmap function in kernel/pid.c in the Linux kernel before 2.6.38.4 allow local users to cause a denial of service (system crash) via a crafted (1) getdents or (2) readdir system call.

From the Ubuntu security team

Tavis Ormandy discovered that the pidmap function did not correctly handle large requests. A local attacker could exploit this to crash the system, leading to a denial of service.
