Title: Apple Mac OS X 'ptrace' Mutex Handling Local Denial of Service Vulnerability
Severity: MODERATE
Description:
Apple Mac OS X is prone to a local denial-of-service vulnerability that is caused by a race condition when handling the 'ptrace' command.
Specifically, the issue occurs because of an error in mutex handling when the software tries to interlock a destroyed mutex.
An attacker can exploit this issue by constructing and executing a malicious binary file.
Exploiting this issue allows local, unprivileged users to crash affected kernels, denying further service to legitimate users.
Affected Products:
- Apple Mac OS X 10.5.6
- Apple Mac OS X 10.5.7
- Apple Mac OS X Server 10.5.6
- Apple Mac OS X Server 10.5.7
