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.

New Wireshark packages that fix various security vulnerabilities are now available. 

This update has been rated as having moderate security impact by the Red Hat Security Response Team. 

Wireshark is a program for monitoring network traffic. 

Users of Wireshark should upgrade to these updated packages containing Wireshark version 0.99.4, which is not vulnerable to these issues.


From Red Hat Security Advisory 2006:0726 :

Several flaws were found in Wireshark's HTTP, WBXML, LDAP, and XOT protocol dissectors.  Wireshark could crash or stop responding if it read a malformed packet off the network.  (CVE-2006-4805, CVE-2006-5468, CVE-2006-5469, CVE-2006-5740)

A single NULL byte heap based buffer overflow was found in Wireshark's MIME Multipart dissector.  Wireshark could crash or possibly execute arbitrary arbitrary code as the user running Wireshark.  (CVE-2006-4574)


From Red Hat Security Advisory 2006:0658 :

Bugs were found in Wireshark's SCSI and SSCOP protocol dissectors. Ethereal could crash or stop responding if it read a malformed packet off the network.  (CVE-2006-4330, CVE-2006-4333)

An off-by-one bug was found in the IPsec ESP decryption preference parser.  Ethereal could crash or stop responding if it read a malformed packet off the network.  (CVE-2006-4331)


From Red Hat Security Advisory 2006:0602 :

In May 2006, Ethereal changed its name to Wireshark.  This update deprecates the Ethereal packages in Red Hat Enterprise Linux 2.1, 3, and 4 in favor of the supported Wireshark packages. 

Several denial of service bugs were found in Ethereal's protocol dissectors.  It was possible for Ethereal to crash or stop responding if it read a malformed packet off the network.  (CVE-2006-3627, CVE-2006-3629, CVE-2006-3631)

Several buffer overflow bugs were found in Ethereal's ANSI MAP, NCP NMAS, and NDPStelnet dissectors.  It was possible for Ethereal to crash or execute arbitrary code if it read a malformed packet off the network. (CVE-2006-3630, CVE-2006-3632)

Several format string bugs were found in Ethereal's Checkpoint FW-1, MQ, XML, and NTP dissectors.  It was possible for Ethereal to crash or execute arbitrary code if it read a malformed packet off the network. (CVE-2006-3628)

Several remote vulnerabilities have been discovered in the Ethereal network scanner, which may lead to the execution of arbitrary code.
The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2006-4333     It was discovered that the Q.2391 dissector is     vulnerable to denial of service caused by memory     exhaustion.

  - CVE-2005-3241     It was discovered that the FC-FCS, RSVP and ISIS-LSP     dissectors are vulnerable to denial of service caused by     memory exhaustion.

  - CVE-2005-3242     It was discovered that the IrDA and SMB dissectors are     vulnerable to denial of service caused by memory     corruption.

  - CVE-2005-3243     It was discovered that the SLIMP3 and AgentX dissectors     are vulnerable to code injection caused by buffer     overflows.

  - CVE-2005-3244     It was discovered that the BER dissector is vulnerable     to denial of service caused by an infinite loop.

  - CVE-2005-3246     It was discovered that the NCP and RTnet dissectors are     vulnerable to denial of service caused by a NULL pointer     dereference.

  - CVE-2005-3248     It was discovered that the X11 dissector is vulnerable     to denial of service caused by a division through zero.

This update also fixes a 64 bit-specific regression in the ASN.1 decoder, which was introduced in a previous DSA.

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.

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

  - 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. (CVE-2006-4333)

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.

New Wireshark packages that fix various security vulnerabilities are now available. Wireshark was previously known as Ethereal.

This update has been rated as having low security impact by the Red Hat Security Response Team.
