A project aimed at disclosing Apple bugs throughout January has revealed its first serious flaw in QuickTime software that could leave Windows and Mac users open to attacks by malicious websites.
The QuickTime flaw launches the Month of Apple Bugs (MOAB), which follows on from efforts such as the Month of Kernel Bugs and the Month of Browser Bugs. The bug was discovered by an anonymous MOAB organiser, known -only as LMH.
The attack can execute malicious code and take over a system. "Exploitation of this issue is trivial," LMH wrote. He supplied a working exploit, which makes the problem all the more dangerous.
The problem hasn't been patched yet. Possible workarounds include uninstalling QuickTime and disabling the rtsp:// handler.
Security advisors, Secunia and FrSIRT both agreed the bug poses an immediate threat.
