DescriptionThe remote host is affected by the vulnerability described in GLSA-200809-17 (Wireshark: Multiple Denials of Service)
The following vulnerabilities were reported:
Multiple buffer overflows in the NCP dissector (CVE-2008-3146).

Invalid read in the tvb_uncompress() function when processing zlib compressed data (CVE-2008-3933).
