Integer overflow in the bitmap (BMP) decoder for Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allow remote attackers to execute arbitrary code via wide bitmap files that trigger heap-based buffer overflows.
Integer overflow in the SOAPParameter object constructor in (1) Netscape version 7.0 and 7.1 and (2) Mozilla 1.6, and possibly earlier versions, allows remote attackers to execute arbitrary code.
Netscape 7.x to 7.2, and possibly other versions, allows remote attackers to spoof arbitrary web sites by injecting content from one window into a target window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability.
The (1) Mozilla 1.6, (2) Firebird 0.7, (3) Firefox 0.8, and (4) Netscape 7.1 web browsers do not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates web site spoofing and other attacks, aka the frame injection vulnerability.
Mozilla Firefox 1.5, Netscape 8.0.4 and 7.2, and K-Meleon before 0.9.12 allows remote attackers to cause a denial of service (CPU consumption and delayed application startup) via a web site with a large title, which is recorded in history.dat but not processed efficiently during startup. NOTE: despite initial reports, the Mozilla vendor does not believe that this issue can be used to trigger a crash or buffer overflow in Firefox. Also, it has been independently reported that Netscape 8.1 does not have this issue.
Netscape Navigator 7.1 allows remote attackers to spoof a legitimate URL in the status bar via A HREF tags with modified "alt" values that point to the legitimate site, combined with an image map whose href points to the malicious site, which facilitates a "phishing" attack.
Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allows remote attackers to perform cross-domain scripting and possibly execute arbitrary code by convincing a user to drag and drop javascript: links to a frame or page in another domain.
The Apple Java plugin, as used in Netscape 7.1 and 7.2, Mozilla 1.7.2, and Firefox 0.9.3 on MacOS X 10.3.5, when tabbed browsing is enabled, does not properly handle SetWindow(NULL) calls, which allows Java applets from one tab to draw to other tabs and facilitates phishing attacks that spoof tabs.
