Heap-based buffer overflow in wiretap/pcapng.c in Wireshark before 1.2 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted capture file.

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2011-0370 advisory.

    - Resolves: CVE -2011-0024 CVE-2011-0538 CVE-2011-1139 CVE-2011-1140       CVE-2011-1141 CVE-2011-1143 #612240

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

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

A heap-based buffer overflow flaw was found in Wireshark. If Wireshark opened a specially crafted capture file, it could crash or, possibly, execute arbitrary code as the user running Wireshark. (CVE-2011-0024)

Several denial of service flaws were found in Wireshark. Wireshark could crash or stop responding if it read a malformed packet off a network, or opened a malicious dump file. (CVE-2010-3445, CVE-2011-0538, CVE-2011-1139, CVE-2011-1140, CVE-2011-1141, CVE-2011-1143)

All running instances of Wireshark must be restarted for the update to take effect.

The remote host is affected by the vulnerability described in GLSA-201110-02 (Wireshark: Multiple vulnerabilities)

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

    A remote attacker could send specially crafted packets on a network       being monitored by Wireshark, entice a user to open a malformed packet       trace file using Wireshark, or deploy a specially crafted Lua script for       use by Wireshark, possibly resulting in the execution of arbitrary code,       or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.
