GNU SASL before 2.2.4 lacks sanitization of a short challenge in gsaslntlmclientstep in the NTLM client, which could result in memory disclosure via a crafted server.

Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group ). Prior to versions 3.4.1, 3.3.1, and 2.6.11, when the security mode is enabled, modifying the DATA Submessage within an SPDP packet sent by a publisher causes an Out-Of-Memory (OOM) condition, resulting in remote termination of Fast-DDS. If t he fields of PIDIDENTITYTOKEN or PIDPERMISSIONSTOKEN in the DATA Submessage are tampered with — specifically by ta mpering with the the vecsize value read by readOctetVector — a 32-bit integer overflow can occur, causing std::vector ::resize to request an attacker-controlled size and quickly trigger OOM and remote process termination. Versions 3.4.1, 3 .3.1, and 2.6.11 patch the issue.
