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
A vulnerability has been identified in Solid Edge SE2020 (All Versions < SE2020MP13), Solid Edge SE2021 (All Versions < SE2021MP3). When opening a specially crafted SEECTCXML file, the application could disclose arbitrary files to remote attackers. This is because of the passing of specially crafted content to the underlying XML parser without taking proper restrictions such as prohibiting an external dtd. (ZDI-CAN-11923)
