Unspecified vulnerability in the DHCP dissector in Wireshark (formerly Ethereal) 0.10.13 through 0.99.2, when run on Windows, allows remote attackers to cause a denial of service (crash) via unspecified vectors that trigger a bug in Glib.

A security problem was fixed in ethereal, which could be used by remote attackers to hang the ethereal process.

CVE-2006-4333: If the SSCOP dissector has a port range configured AND the SSCOP payload protocol is Q.2931, a malformed packet could make the Q.2931 dissector use up available memory. No port range is configured by default.

The vulnerabilities tracked by the Mitre CVE IDs CVE-2006-4330 (SCSI dissector), CVE-2006-4331 (ESP decryption), CVE-2006-4332 (DHCP dissector) do not affect our shipped ethereal releases.

Vulnerabilities in the SCSI, DHCP, and SSCOP dissectors were discovered in versions of wireshark less than 0.99.3, as well as an off-by-one error in the IPsec ESP preference parser if compiled with ESP decryption support.

This updated provides wireshark 0.99.3a which is not vulnerable to these issues.

The remote host is affected by the vulnerability described in GLSA-200608-26 (Wireshark: Multiple vulnerabilities)

    The following vulnerabilities have been discovered in Wireshark.
    Firstly, if the IPsec ESP parser is used it is susceptible to     off-by-one errors, this parser is disabled by default; secondly, the     SCSI dissector is vulnerable to an unspecified crash; and finally, the     Q.2931 dissector of the SSCOP payload may use all the available memory     if a port range is configured. By default, no port ranges are     configured.
  Impact :

    An attacker might be able to exploit these vulnerabilities, resulting     in a crash or the execution of arbitrary code with the permissions of     the user running Wireshark, possibly the root user.
  Workaround :

    Disable the SCSI and Q.2931 dissectors with the 'Analyse' and 'Enabled     protocols' menus. Make sure the ESP decryption is disabled, with the     'Edit -> Preferences -> Protocols -> ESP' menu.
