Apple QuickTime exploit in the wild
Published: 03 Dec 2007 12:48 GMT
Symantec has found active exploit code in the wild for an unpatched Apple QuickTime vulnerability.
Researcher Joji Hamada wrote in Symantec's Security Response Weblog on Saturday that the company had seen an active exploit for the vulnerability in Apple's media-streaming program that could lead to users downloading Trojan software.
Hamada said the exploit code was found on a compromised porn site that redirects users to a site hosting malware called "Downloader". Downloader is a Trojan that causes compromised machines to download other malware from the internet. Symantec rates Downloader as "very low" risk.
No patch is currently available for the vulnerability, which affects version 7.x, and which lies in a boundary error when QuickTime processes Real Time Streaming Protocol (RTSP) replies.
Symantec is advising concerned IT professionals to run web browsers at the highest security settings possible, disable Apple QuickTime as a registered RTSP protocol handler, and filter outgoing activity over common RTSP ports, including TCP port 554 and UDP ports 6970-6999.
Proof of concept code was published when the vulnerability was disclosed by security research company Secunia last week.
