Summaryinfo

A vulnerability was found in eProsima Fast-DDS up to 2.6.10/3.3.0/3.4.0. It has been rated as critical. Impacted is an unknown function. Performing a manipulation of the argument PID_IDENTITY_TOKEN/PID_PERMISSIONS_TOKEN results in heap-based overflow. This vulnerability is known as CVE-2025-62601. Remote exploitation of the attack is possible. No exploit is available. Upgrading the affected component is advised.

Detailsinfo

A vulnerability was found in eProsima Fast-DDS up to 2.6.10/3.3.0/3.4.0. It has been classified as critical. This affects an unknown function. The manipulation of the argument PID_IDENTITY_TOKEN/PID_PERMISSIONS_TOKEN with an unknown input leads to a heap-based overflow vulnerability. CWE is classifying the issue as CWE-122. 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(). This is going to have an impact on availability. The summary by CVE is:

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.

The advisory is shared at security-tracker.debian.org. This vulnerability is uniquely identified as CVE-2025-62601 since 10/16/2025. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

Upgrading to version 2.6.11, 3.3.1 or 3.4.1 eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2025-206631). If you want to get the best quality for vulnerability data then you always have to consider VulDB.
