MongoDB PHP driver vulnerabilities

A deserialization vulnerability in the command monitoring support of the MongoDB PHP Driver can cause class names from document content to be honored when building monitoring events. An attacker controlling data in database operations may instantiate application classes implementing the persistable interface and invoke their unserialize method.

An out-of-bounds read in the BSON decoding component of the MongoDB PHP driver may allow an unauthenticated party who supplies specially formed input to have a small amount of adjacent process memory copied into an error message that is returned to application code. This may result in unintended disclosure of limited memory contents.

A stack exhaustion vulnerability in the MongoDB PHP driver can cause application crashes when processing deeply nested BSON documents in unusual circumstances when the source of these BSON documents is not MongoDB Server.
