Mozilla : Security Vulnerabilities, CVEs, Published In October 2009 (Denial of service)

Multiple unspecified vulnerabilities in the JavaScript 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.

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.

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 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.

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.

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 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.

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.
