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
The Eaton's easySoft software v7.xx prior to v7.22 are susceptible to Out-of-bounds remote code execution vulnerability. A malicious entity can execute a malicious code or make the application crash by tricking user to upload the malformed .E70 file in the application. The vulnerability arises due to improper validation and parsing of the E70 file content by the application.
