The oggplay_data_handle_theora_frame function in media/liboggplay/src/liboggplay/oggplay_data.c in liboggplay, as used in Mozilla Firefox 3.5.x before 3.5.4, attempts to reuse an earlier frame data structure upon encountering a decoding error for the first frame, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or possibly execute arbitrary code via a crafted .ogg video file.

Multiple unspecified vulnerabilities in libvorbis, as used in Mozilla Firefox 3.5.x before 3.5.4, allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via unknown vectors. NOTE: this might overlap CVE-2009-2663.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 3.5.x before 3.5.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Multiple unspecified vulnerabilities in liboggz before cf5feeaab69b05e24, as used in Mozilla Firefox 3.5.x before 3.5.4, allow remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla Firefox before 3.0.15 and 3.5.x before 3.5.4, and SeaMonkey before 2.0, does not properly handle a right-to-left override (aka RLO or U+202E) Unicode character in a download filename, which allows remote attackers to spoof file extensions via a crafted filename, as demonstrated by displaying a non-executable extension for an executable file.

content/html/document/src/nsHTMLDocument.cpp in Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4 allows user-assisted remote attackers to bypass the Same Origin Policy and read an arbitrary content selection via the document.getSelection function.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Use-after-free vulnerability in Mozilla Firefox 3.5.x before 3.5.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code by creating JavaScript web-workers recursively.

layout/base/nsCSSFrameConstructor.cpp in the browser engine in Mozilla Firefox 3.0.x before 3.0.15 does not properly handle first-letter frames, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unspecified vectors.

The XPCVariant::VariantDataToJS function in the XPCOM implementation in Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4 does not enforce intended restrictions on interaction between chrome privileged code and objects obtained from remote web sites, which allows remote attackers to execute arbitrary JavaScript with chrome privileges via unspecified method calls, related to "doubly-wrapped objects."
