Wireshark was updated to version 1.4.4 to fix several security issues

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.

Several security bugs were fixed in this release :

  - CVE-2011-0538: memory corruption when reading a     malformed pcap file

    - CVE-2010-3445: stack overflow in BER dissector

    - CVE-2011-1143: NULL pointer dereference causing       application crash when reading malformed pcap file

    - CVE-2011-1140: Multiple stack consumption       vulnerabilities caused DoS via crafted SMB or CLDAP       packet

    - CVE-2011-1138: Off-by-one error in the       dissect_6lowpan_iphc function causes application crash       (Denial Of Service)

    - CVE-2011-1139: Denial Of Service (application crash)       via a pcap-ng file that contains a large packet-length       field

    - CVE-2011-0713: heap-based buffer overflow when reading       malformed Nokia DCT3 phone signaling traces

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.

Updated wireshark packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Wireshark is a program for monitoring network traffic. Wireshark was previously known as Ethereal.

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)

Users of Wireshark should upgrade to these updated packages, which contain backported patches to correct these issues. All running instances of Wireshark must be restarted for the update to take effect.

Huzaifa Sidhpurwala, Joernchen, and Xiaopeng Zhang discovered several vulnerabilities in the Wireshark network traffic analyzer.
Vulnerabilities in the DCT3, LDAP and SMB dissectors and in the code to parse pcag-ng files could lead to denial of service or the execution of arbitrary code.

This advisory updates wireshark to the latest version (1.2.15), fixing several security issues :

Wireshark 1.5.0, 1.4.3, and earlier frees an uninitialized pointer during processing of a .pcap file in the pcap-ng format, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a malformed file (CVE-2011-0538).

Heap-based buffer overflow in wiretap/dct3trace.c in Wireshark 1.2.0 through 1.2.14 and 1.4.0 through 1.4.3 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a long record in a Nokia DCT3 trace file (CVE-2011-0713).

wiretap/pcapng.c in Wireshark 1.2.0 through 1.2.14 and 1.4.0 through 1.4.3 allows remote attackers to cause a denial of service (application crash) via a pcap-ng file that contains a large packet-length field (CVE-2011-1139).

Multiple stack consumption vulnerabilities in the dissect_ms_compressed_string and dissect_mscldap_string functions in Wireshark 1.0.x, 1.2.0 through 1.2.14, and 1.4.0 through 1.4.3 allow remote attackers to cause a denial of service (infinite recursion) via a crafted (1) SMB or (2) Connection-less LDAP (CLDAP) packet (CVE-2011-1140).

epan/dissectors/packet-ldap.c in Wireshark 1.0.x, 1.2.0 through 1.2.14, and 1.4.0 through 1.4.3 allows remote attackers to cause a denial of service (memory consumption) via (1) a long LDAP filter string or (2) an LDAP filter string containing many elements (CVE-2011-1141).

Stack consumption vulnerability in the dissect_ber_choice function in the BER dissector in Wireshark 1.2.x through 1.2.15 and 1.4.x through 1.4.4 might allow remote attackers to cause a denial of service (infinite loop) via vectors involving self-referential ASN.1 CHOICE values (CVE-2011-1142).

epan/dissectors/packet-ntlmssp.c in the NTLMSSP dissector in Wireshark before 1.4.4 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted .pcap file (CVE-2011-1143).

The updated packages have been upgraded to the latest 1.2.x version (1.2.15) and patched to correct these issues.
