CVE-2008-1615

Published: 8 May 2008

Linux kernel 2.6.18, and possibly other versions, when running on AMD64 architectures, allows local users to cause a denial of service (crash) via certain ptrace calls.

From the Ubuntu Security Team

Jan Kratochvil discovered that PTRACE did not correctly handle certain calls when running under 64bit kernels. A local attacker could exploit this to crash the system, leading to a denial of service.
