The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200708-03
(libarchive (formerly named as bsdtar): Multiple PaX Extension Header Vulnerabilities)
CPNI, CERT-FI, Tim Kientzle, and Colin Percival reported a buffer
overflow (CVE-2007-3641), an infinite loop (CVE-2007-3644), and a NULL
pointer dereference (CVE-2007-3645) within the processing of archives
having corrupted PaX extension headers.
An attacker can trick a user or automated system to process an archive
with malformed PaX extension headers into execute arbitrary code, crash
an application using the library, or cause a high CPU load.
There is no known workaround at this time.
