Here are some of the more interesting bugs from last week’s BugBlog.
The Internet Storm Center has issued a warning about Trojan horse programs hiding within Web "postcards." You may get an email message that says something like, "You have received a virtual postcard from a family member," with a link. Clicking the link will install the Trojan. Another set of threats may come masquerading as greeting cards from a legitimate card company such as Blue Mountain or American Greetings. (That’s just great — now I’ll have to go back to buying snail-mail cards.) Read more about this at
apparently, part of this bug stretches back to 1997. They have a fix, but it has not yet been released. The bug was reported by Secunia at http://secunia.com/advisories/14820/ from Russian sources.
Adobe Acrobat 7.0 and earlier and the Adobe Reader 7.0 and earlier have a bug in the way they interact with an Internet Explorer ActiveX control. If this control is invoked directly by a web page, an attacker may be able to learn whether certain local files exist. This will only happen on a computer that is running Microsoft Internet Explorer. According to Adobe, the file contents are not exposed. This has been fixed in the Adobe Acrobat and Acrobat Reader 7.0.1 update.
