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 maliciously crafted DWG file can be used to write beyond the allocated buffer while parsing DWG files. The vulnerability exists because the application fails to handle a crafted DWG file, which causes an unhandled exception. An attacker can leverage this vulnerability to execute arbitrary code.
