The file-download dialog in Mozilla Firefox before 44.0 on OS X enables a certain button too quickly, which allows remote attackers to conduct clickjacking attacks via a crafted web site that triggers a single-click action in a situation where a double-click action was intended.
Mozilla Firefox before 44.0 stores cookies with names containing vertical tab characters, which allows remote attackers to obtain sensitive information by reading HTTP Cookie headers. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-7208.
Mozilla Firefox before 44.0 on Android allows remote attackers to spoof the address bar via a data: URL that is mishandled during (1) shortcut opening or (2) BOOKMARK intent processing.
The s_mp_div function in lib/freebl/mpi/mpi.c in Mozilla Network Security Services (NSS) before 3.21, as used in Mozilla Firefox before 44.0, improperly divides numbers, which might make it easier for remote attackers to defeat cryptographic protection mechanisms by leveraging use of the (1) mp_div or (2) mp_exptmod function.
The protocol-handler dialog in Mozilla Firefox before 44.0 allows remote attackers to conduct clickjacking attacks via a crafted web site that triggers a single-click action in a situation where a double-click action was intended.
Buffer overflow in the BufferSubData function in Mozilla Firefox before 44.0 and Firefox ESR 38.x before 38.6 allows remote attackers to execute arbitrary code via crafted WebGL content.
Integer overflow in the image-deinterlacing functionality in Mozilla Firefox before 44.0 allows remote attackers to cause a denial of service (memory consumption or application crash) via a crafted GIF image.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 44.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to uninitialized memory encountered during brotli data compression, and other vectors.
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 44.0 and Firefox ESR 38.x before 38.6 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Mozilla Network Security Services (NSS) before 3.20.2, as used in Mozilla Firefox before 43.0.2 and Firefox ESR 38.x before 38.5.2, does not reject MD5 signatures in Server Key Exchange messages in TLS 1.2 Handshake Protocol traffic, which makes it easier for man-in-the-middle attackers to spoof servers by triggering a collision.
