## Technical details

A heap-based buffer overflow vulnerability (CWE-122) exists in the Core Libraries of RTI Connext Professional. The flaw is triggered by improper handling of 'Overflow Variables and Tags' during data processing. An unauthenticated attacker can exploit this over the network without user interaction to cause a crash (denial of service) or potentially achieve limited unauthorized modification of data. The vulnerability affects multiple long-term support (LTS) versions, and RTI has released patches for active versions including 7.3.1.3 and 7.7.0.

## Affected products
