The dissect_lbmr_pser function in epan/dissectors/packet-lbmr.c in the LBMR dissector in Wireshark 1.12.x before 1.12.5 does not properly track the current offset, which allows remote attackers to cause a denial of service (infinite loop) via a crafted packet.

The remote host is affected by the vulnerability described in GLSA-201510-03 (Wireshark: Multiple vulnerabilities)

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

    A remote attacker could possibly cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

Multiple vulnerabilities were discovered in the dissectors/parsers for LBMR, web sockets, WCP, X11, IEEE 802.11 and Android Logcat, which could result in denial of service.

Wireshark development team reports :

(Bug 11188) CVE-2015-3815

Wireshark was updated to 1.12.5 to fix security issues and bugs.

The following vulnerabilities have been fixed :

  - CVE-2015-3808, CVE-2015-3809: The LBMR dissector could     go into an infinite loop. (wnpa-sec-2015-12)

  - CVE-2015-3810: The WebSocket dissector could recurse     excessively. (wnpa-sec-2015-13)

  - CVE-2015-3811: The WCP dissector could crash while     decompressing data. (wnpa-sec-2015-14)

  - CVE-2015-3812: The X11 dissector could leak memory.
    (wnpa-sec-2015-15)

  - CVE-2015-3813: The packet reassembly code could leak     memory. (wnpa-sec-2015-16)

  - CVE-2015-3814: The IEEE 802.11 dissector could go into     an infinite loop. (wnpa-sec-2015-17)

  - CVE-2015-3815: The Android Logcat file parser could     crash. (wnpa-sec-2015-18)

The version of Wireshark installed on the remote Windows host is 1.10.x prior to 1.10.14, or 1.12.x prior to 1.12.5. It is, therefore, affected by various denial of service vulnerabilities in the following items :

  - LBMR dissector (CVE-2015-3808, CVE-2015-3809)

  - WebSocket dissector (CVE-2015-3810)

  - WCP dissector (CVE-2015-3811)

  - X11 dissector (CVE-2015-3812)

  - Packet reassembly code (CVE-2015-3813)

  - IEEE 802.11 dissector (CVE-2015-3814)

  - Android Logcat file parser (CVE-2015-3815,     CVE-2015-3906)

A remote attacker can exploit these vulnerabilities to cause Wireshark to crash or consume excessive CPU resources, either by injecting a specially crafted packet onto the wire or by convincing a user to read a malformed packet trace or PCAP file.

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