Technical 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.

Remediation

Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
