Detailsinfo

A vulnerability was found in eProsima Fast-DDS up to 2.6.10/3.3.0/3.4.0. It has been declared as problematic. Affected by this vulnerability is some unknown processing. The manipulation of the argument PID_IDENTITY_TOKEN/PID_PERMISSION_TOKEN with an unknown input leads to a integer overflow vulnerability. The CWE definition for the vulnerability is CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. As an impact it is known to affect 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 an Out-Of-Memory (OOM) condition, resulting in remote termination of Fast-DDS. If t he fields of PID_IDENTITY_TOKEN or PID_PERMISSION_TOKEN in the DATA Submessage — specifically by tampering with the length field in readBinaryPropertySeq — are modified, an integer overflow occurs, leading to an OOM during the resize operation. 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 known as CVE-2025-62600 since 10/16/2025. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. 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. Applying the patch 354218514d32beac963ff5c306f1cf159ee37c5f is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.
