CVE-2009-1834 2 Mozilla, Redhat 3 Firefox, Seamonkey, Enterprise Linux 2026-04-23 N/A
Visual truncation vulnerability in netwerk/dns/src/nsIDNService.cpp in Mozilla Firefox before 3.0.11 and SeaMonkey before 1.1.17 allows remote attackers to spoof the location bar via an IDN with invalid Unicode characters that are displayed as whitespace, as demonstrated by the \u115A through \u115E characters.
CVE-2006-5633 1 Mozilla 2 Firefox, Seamonkey 2026-04-23 N/A
Firefox 1.5.0.7 and 2.0, and Seamonkey 1.1b, allows remote attackers to cause a denial of service (crash) by creating a range object using createRange, calling selectNode on a DocType node (DOCUMENT_TYPE_NODE), then calling createContextualFragment on the range, which triggers a null dereference. NOTE: the original Bugtraq post mentioned that code execution was possible, but followup analysis has shown that it is only a null dereference.
CVE-2009-1835 2 Mozilla, Redhat 3 Firefox, Seamonkey, Enterprise Linux 2026-04-23 N/A
Mozilla Firefox before 3.0.11 and SeaMonkey before 1.1.17 associate local documents with external domain names located after the file:// substring in a URL, which allows user-assisted remote attackers to read arbitrary cookies via a crafted HTML document, as demonstrated by a URL with file://example.com/C:/ at the beginning.
CVE-2006-5464 2 Mozilla, Redhat 4 Firefox, Seamonkey, Thunderbird and 1 more 2026-04-23 N/A
Multiple unspecified vulnerabilities in the layout engine in Mozilla Firefox before 1.5.0.8, Thunderbird before 1.5.0.8, and SeaMonkey before 1.0.6 allow remote attackers to cause a denial of service (crash) via unspecified vectors.
CVE-2006-5463 2 Mozilla, Redhat 4 Firefox, Seamonkey, Thunderbird and 1 more 2026-04-23 N/A
Unspecified vulnerability in Mozilla Firefox before 1.5.0.8, Thunderbird before 1.5.0.8, and SeaMonkey before 1.0.6 allows remote attackers to execute arbitrary JavaScript bytecode via unspecified vectors involving modification of a Script object while it is executing.
CVE-2009-1836 2 Mozilla, Redhat 4 Firefox, Seamonkey, Thunderbird and 1 more 2026-04-23 N/A
Mozilla Firefox before 3.0.11, Thunderbird before 2.0.0.22, and SeaMonkey before 1.1.17 use the HTTP Host header to determine the context of a document provided in a non-200 CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack.
CVE-2007-0800 2 Mozilla, Redhat 2 Firefox, Enterprise Linux 2026-04-23 N/A
Cross-zone vulnerability in Mozilla Firefox 1.5.0.9 considers blocked popups to have an internal zone origin, which allows user-assisted remote attackers to cross zone restrictions and read arbitrary file:// URIs by convincing a user to show a blocked popup.
CVE-2007-0777 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Firefox, Seamonkey and 2 more 2026-04-23 N/A
The JavaScript engine in Mozilla Firefox before 1.5.0.10 and 2.x before 2.0.0.2, Thunderbird before 1.5.0.10, and SeaMonkey before 1.0.8 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via certain vectors that trigger memory corruption.

Mozilla Firefox before 2.0.0.12 and SeaMonkey before 1.1.8 allows user-assisted remote attackers to trick the user into uploading arbitrary files via label tags that shift focus to a file input field, aka "focus spoofing."
