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
Stack-based buffer overflow on Rockwell Automation Allen-Bradley MicroLogix 1100 devices A through 15.000 and B before 15.002 allows remote attackers to execute arbitrary code via a crafted web request.
