Heap-based buffer overflow in Mozilla Network Security Services (NSS) before 3.19.2.3 and 3.20.x and 3.21.x before 3.21.1, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, allows remote attackers to execute arbitrary code via crafted ASN.1 data in an X.509 certificate.

Off-by-one error in the pcapng_read function in wiretap/pcapng.c in the pcapng file parser in Wireshark 1.10.x before 1.10.13 and 1.12.x before 1.12.4 allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via an invalid Interface Statistics Block (ISB) interface ID in a crafted packet.

Integer overflow in the dissect_tnef function in epan/dissectors/packet-tnef.c in the TNEF dissector in Wireshark 1.10.x before 1.10.13 and 1.12.x before 1.12.4 allows remote attackers to cause a denial of service (infinite loop) via a crafted length field in a packet.

epan/dissectors/packet-wcp.c in the WCP dissector in Wireshark 1.10.x before 1.10.13 and 1.12.x before 1.12.4 does not properly initialize a data structure, which allows remote attackers to cause a denial of service (out-of-bounds read and application crash) via a crafted packet that is improperly handled during decompression.

Mozilla Firefox before 36.0 does not properly recognize the equivalence of domain names with and without a trailing . (dot) character, which allows man-in-the-middle attackers to bypass the HPKP and HSTS protection mechanisms by constructing a URL with this character and leveraging access to an X.509 certificate for a domain with this character.

Stack-based buffer underflow in the mozilla::MP3FrameParser::ParseBuffer function in Mozilla Firefox before 36.0 allows remote attackers to obtain sensitive information from process memory via a malformed MP3 file that improperly interacts with memory allocation during playback.

Buffer overflow in libstagefright in Mozilla Firefox before 36.0 allows remote attackers to execute arbitrary code via a crafted MP4 video that is improperly handled during playback.

The UITour::onPageEvent function in Mozilla Firefox before 36.0 does not ensure that an API call originates from a foreground tab, which allows remote attackers to conduct spoofing and clickjacking attacks by leveraging access to a UI Tour web site.

The WebRTC subsystem in Mozilla Firefox before 36.0 recognizes turns: and stuns: URIs but accesses the TURN or STUN server without using TLS, which makes it easier for man-in-the-middle attackers to discover credentials by spoofing a server and completing a brute-force attack within a short time window.

The WebGL implementation in Mozilla Firefox before 36.0 does not properly allocate memory for copying an unspecified string to a shader's compilation log, which allows remote attackers to cause a denial of service (application crash) via crafted WebGL content.
