CVE-2008-2365

Priority
Medium
Description
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.
Ubuntu-Description
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.
