Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and Thunderbird before 38.1 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 3.19, as used in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, Thunderbird before 38.1, and other products, does not properly determine state transitions for the TLS state machine, which allows man-in-the-middle attackers to defeat cryptographic protection mechanisms by blocking messages, as demonstrated by removing a forward-secrecy property by blocking a ServerKeyExchange message, aka a "SMACK SKIP-TLS" issue.

The ndisc_router_discovery function in net/ipv6/ndisc.c in the Neighbor Discovery (ND) protocol implementation in the IPv6 stack in the Linux kernel before 3.19.6 allows remote attackers to reconfigure a hop-limit setting via a small hop_limit value in a Router Advertisement (RA) message.

Unspecified vulnerability in Oracle MySQL Server 5.5.42 and earlier, and 5.6.23 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server : Optimizer.

Unspecified vulnerability in Oracle MySQL Server 5.5.41 and earlier, and 5.6.22 and earlier, allows remote authenticated users to affect availability via vectors related to DDL.

Unspecified vulnerability in Oracle MySQL Server 5.5.41 and earlier, and 5.6.22 and earlier, allows remote attackers to affect availability via unknown vectors related to Server : Security : Privileges.

Unspecified vulnerability in Oracle MySQL Server 5.5.42 and earlier, and 5.6.23 and earlier, allows remote authenticated users to affect availability via vectors related to DDL.

Unspecified vulnerability in Oracle MySQL Server 5.5.42 and earlier, and 5.6.23 and earlier, allows remote authenticated users to affect availability via unknown vectors related to Server : Federated.

Unspecified vulnerability in Oracle MySQL Server 5.5.41 and earlier, and 5.6.22 and earlier, allows remote authenticated users to affect availability via vectors related to InnoDB : DML.

The force printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.
