Description
Several flaws were found in the processing of malformed web content. A web
page containing malicious content could cause Firefox to crash or,
potentially, execute arbitrary code with the privileges of the user running
Firefox.
A heap-based buffer overflow flaw was found in the way Firefox processed
compressed XML data. An attacker could create specially crafted compressed
XML content that, when processed by Firefox, could cause it to crash or
execute arbitrary code with the privileges of the user running Firefox.
