The AutoFill feature in Apple Safari 2.0.4 does not properly verify that all automatically populated form fields are visible to the user, which allows remote attackers to obtain sensitive information, such as usernames and passwords, via input fields of zero width, a variant of CVE-2006-6077.

WebCore in Apple Mac OS X 10.3.9 and 10.4 through 10.4.7 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via crafted HTML that triggers a "memory management error" in WebKit, possibly due to a buffer overflow, as originally reported for the KHTMLParser::popOneBlock function in Apple Safari 2.0.4 using Javascript that changes document.body.innerHTML within a DIV tag.
