Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
Rockwell Automation ThinManager ThinServer versions 11.0.0 - 13.0.0 is vulnerable to a heap-based buffer overflow. An attacker could send a specifically crafted TFTP or HTTPS request, causing a heap-based buffer overflow that crashes the ThinServer process. If successfully exploited, this could expose the server to arbitrary remote code execution.
