The remote host is missing updates announced in advisory GLSA 200406-18.

All gzip users should upgrade to the latest stable version: # emerge sync # emerge -pv '>=app-arch/gzip-1.3.3-r4' # emerge '>=app-arch/gzip-1.3.3-r4' Additionally, once the upgrade is complete, all self extracting files created with earlier versions gzexe should be recreated, since the vulnerability is actually embedded in those executables. http://www.securityspace.com/smysecure/catid.html?in=GLSA%20200406-18 http://bugs.gentoo.org/show_bug.cgi?id=54890
