eprosima Fast DDS affected by Out-of-Memory in readPropertySeq via Manipulated DATA Submessage when DDS Security is enabled

eprosima Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group). Prior to 2.6.11, 2.14.6, 3.2.4, 3.3.1, and 3.4.1, 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 the fields of PID_IDENTITY_TOKEN or PID_PERMISSION_TOKEN in the DATA Submessage — specifically by tampering with the length field in readPropertySeq — are modified, an integer overflow occurs, leading to an OOM during the resize operation. This vulnerability is fixed in 2.6.11, 2.14.6, 3.2.4, 3.3.1, and 3.4.1.

整数溢出或超界折返

Fast-DDS 输入验证错误漏洞

Fast-DDS是eProsima开源的一个完整的DDS系统。 Fast-DDS 3.4.1之前版本、3.3.1之前版本和2.6.11之前版本存在输入验证错误漏洞，该漏洞源于修改DATA子消息中的PID_IDENTITY_TOKEN或PID_PERMISSION_TOKEN字段长度导致整数溢出，可能引发内存耗尽和远程进程终止。
