CVE-2005-0255 2 Mozilla, Redhat 4 Firefox, Mozilla, Thunderbird and 1 more 2026-04-16 N/A
String handling functions in Mozilla 1.7.3, Firefox 1.0, and Thunderbird before 1.0.2, such as the nsTSubstring_CharT::Replace function, do not properly check the return values of other functions that resize the string, which allows remote attackers to cause a denial of service and possibly execute arbitrary code by forcing an out-of-memory state that causes a reallocation to fail and return a pointer to a fixed address, which leads to heap corruption.
CVE-2006-0297 1 Mozilla 3 Firefox, Seamonkey, Thunderbird 2026-04-16 N/A
Multiple integer overflows in Mozilla Firefox 1.5, Thunderbird 1.5 if Javascript is enabled in mail, and SeaMonkey before 1.0 might allow remote attackers to execute arbitrary code via the (1) EscapeAttributeValue in jsxml.c for E4X, (2) nsSVGCairoSurface::Init in SVG, and (3) nsCanvasRenderingContext2D.cpp in Canvas.
CVE-2006-2776 2 Mozilla, Redhat 3 Firefox, Thunderbird, Enterprise Linux 2026-04-16 N/A
Certain privileged UI code in Mozilla Firefox and Thunderbird before 1.5.0.4 calls content-defined setters on an object prototype, which allows remote attackers to execute code at a higher privilege than intended.
CVE-2006-2775 1 Mozilla 2 Firefox, Thunderbird 2026-04-16 N/A
Mozilla Firefox and Thunderbird before 1.5.0.4 associates XUL attributes with the wrong URL under certain unspecified circumstances, which might allow remote attackers to bypass restrictions by causing a persisted string to be associated with the wrong URL.
