Publication date 30 June 2008

Last updated 24 July 2024

Ubuntu priority

Race condition in the ptrace and utrace support in the Linux kernel 2.6.9 through 2.6.25, as used in Red Hat Enterprise Linux (RHEL) 4, allows local users to cause a denial of service (oops) via a long series of PTRACE_ATTACH ptrace calls to another user's process that trigger a conflict between utrace_detach and report_quiescent, related to "late ptrace_may_attach() check" and "race around &dead_engine_ops setting," a different vulnerability than CVE-2007-0771 and CVE-2008-1514. NOTE: this issue might only affect kernel versions before 2.6.16.x.

From the Ubuntu Security Team

A race condition was discovered between ptrace and utrace in the kernel. A local attacker could exploit this to crash the system, leading to a denial of service.
