CVE-2018-17141

Name of the Vulnerable Software and Affected Versions HylaFAX version 6.0.6 HylaFAX+ version 5.6.0

Description The issue allows remote attackers to execute arbitrary code via a dial-in session that provides a FAX page with the JPEG bit enabled. This is mishandled in the FaxModem::writeECMData() function in the faxd/CopyQuality.c++ file.
