CVE-2025-62600

Severity CVSS v4.0:
LOW
Type:
CWE-125 Out-of-bounds Read

Description

Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group<br /> ). 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 <br /> SPDP packet sent by a publisher causes an Out-Of-Memory (OOM) condition, resulting in remote termination of Fast-DDS. If t<br /> he fields of PID_IDENTITY_TOKEN or PID_PERMISSION_TOKEN in the DATA Submessage — specifically by tampering with the length<br /> field in readBinaryPropertySeq — are modified, an integer overflow occurs, leading to an OOM during the resize operation.<br /> Versions 3.4.1, 3.3.1, and 2.6.11 patch the issue.
