CVE-2025-62601

FastDDS has heap buffer overflow in readString via Manipulated DATA Submessage when DDS Security is enabled

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.

CWE-122 Heap-based Buffer Overflow

A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().

CWE-787 Out-of-bounds Write

The product writes data past the end, or before the beginning, of the intended buffer.
