The dissect_frame function in epan/dissectors/packet-frame.c in the frame metadissector in Wireshark 1.10.x before 1.10.8 interprets a negative integer as a length value even though it was intended to represent an error condition, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The dissect_frame function in epan/dissectors/packet-frame.c in the frame metadissector in Wireshark     1.10.x before 1.10.8 interprets a negative integer as a length value even though it was intended to     represent an error condition, which allows remote attackers to cause a denial of service (application     crash) via a crafted packet. (CVE-2014-4020)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Solaris system is missing necessary patches to address security updates :

  - The dissect_frame function in     epan/dissectors/packet-frame.c in the frame     metadissector in Wireshark 1.10.x before 1.10.8     interprets a negative integer as a length value even     though it was intended to represent an error condition,     which allows remote attackers to cause a denial of     service (application crash) via a crafted packet.
    (CVE-2014-4020)

The remote host is affected by the vulnerability described in GLSA-201406-33 (Wireshark: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Wireshark. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker can cause arbitrary code execution or a Denial of       Service condition via a specially crafted packet.
  Workaround :

    There is no known workaround at this time.

wireshark was updated to version 1.10.8 to fix a possible DoS in the frame metadissector (CVE-2014-4020).

fix frame metadissector

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The installed version of Wireshark 1.10.x is a version prior to 1.10.8. It is, therefore, affected by a denial of service vulnerability. A flaw exists with the Metadissector dissector when handling a malformed packet that could allow a remote attacker to crash Wireshark.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
