Name of the Vulnerable Software and Affected Versions Varnish HTTP Cache versions 4.1.x through 4.1.8 Varnish HTTP Cache versions 5.x through 5.2.0

Description The issue allows remote attackers to obtain sensitive information from process memory due to a VFP GetStorage buffer being larger than intended in certain circumstances involving -sfile Stevedore transient objects.
