FastDDS has heap buffer overflow in readString via Manipulated DATA Submessage when DDS Security is enabled
Summary
FastDDS has heap buffer overflow in readString via Manipulated DATA Submessage when DDS Security is enabled
Original description
The description as published by the source.
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 a heap buffer overflow, resulting in remote termination of Fast-DDS. If the fields
of PID_IDENTITY_TOKEN or PID_PERMISSIONS_TOKEN in the DATA Submessage — specifically by tampering with the str_size
value read by readString (called from readBinaryProperty) — are modified, a 32-bit integer overflow can occur, causing
std::vector::resize to use an attacker-controlled size and quickly trigger heap buffer overflow and remote process term
ination. Versions 3.4.1, 3.3.1, and 2.6.11 patch the issue.
