in brief Legitimate Web sites hosting Adobe Flash Player content may be compromised to embed JavaScript that redirects users to a Chinese malware server, says Symantec. Affected versions of Adobe Flash Player include 9.0.124.0 (latest version) and 9.0.115.0.
Symantec says that under certain conditions embedded JavaScript within the player will redirect users to dota11.cn. In an alert on Tuesday, Symantec said specific details about the vulnerability exploited were unknown, and initial testing of the in-the-wild exploit showed it to be unreliable. Nonetheless, Symantec said it had identified at least one commercial site, www.bridgettwalther.com, which is a horoscope Web site, but that the embedded malicious code has since been removed.

Symantec recommends that users use script-disabling plug-ins such as NoScript for Firefox to prevent embedded Flash scripts from being loaded.
