CVE-2005-3783

Linux Kernel < 2.6.14.2 - Denial of Service via CLONE_THREAD Ptrace Attachment

Title source: llm

Description

The ptrace functionality (ptrace.c) in Linux kernel 2.6 before 2.6.14.2, using CLONE_THREAD, does not use the thread group ID to check whether it is attaching to itself, which allows local users to cause a denial of service (crash).
