Netscape browsers v4.73 and below can be tricked into executing arbitrary assembly code by a malicious web site. In the case of Netscape Mail or News, the attack may be performed via a mail message or a news article, as well. A bug in the way Netscape browsers use the Independent JPEG Group's decoder library can cause the JPEG stream to be read onto the heap. Exploiting this vulnerability into executing arbitrary code is non-trivial, but possible on some platforms.
