概要
FastDDS has heap buffer overflow in readData via Manipulated DATA Submessage when DDS Security is enabled
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
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 are tampered with — specially readOctetVector
reads an unchecked vecsize that is propagated unchanged into readData as the length parameter — the attacker-contro
lled vecsize can trigger a 32-bit integer overflow during the length calculation. That overflow can cause large alloca
tion attempt that quickly leads to OOM, enabling a remotely-triggerable denial-of-service and remote process termination.
Versions 3.4.1, 3.3.1, and 2.6.11 patch the issue.
