SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200506-23 (Clam AntiVirus: Denial of Service vulnerability)
Andrew Toller and Stefan Kanthak discovered that a flaw in libmspack's Quantum archive decompressor renders Clam AntiVirus vulnerable to a Denial of Service attack.
A remote attacker could exploit this vulnerability to cause a Denial of Service by sending a specially crafted Quantum archive to the server.
There is no known workaround at this time.
