CVE-2011-1593
Published: 03 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.
