Apple's QuickTime software has a highly serious bug that could leave Windows and Mac users open to attacks by malicious websites, according to a project aimed at disclosing Apple bugs throughout January.
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 LMH, a MOAB organizer who hasn't disclosed his name.
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.
Secunia and FrSIRT both agreed the bug poses an immediate threat.
