Unspecified vulnerability in the SSH dissector in Wireshark (aka Ethereal) 0.9.10 to 0.99.0 allows remote attackers to cause a denial of service (infinite loop) via unknown attack vectors.

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)

This update fixes several security related bugs ranging from crashes to arbitrary code execution. (CVE-2006-3627 / CVE-2006-3628 / CVE-2006-3629 / CVE-2006-3630 / CVE-2006-3631 / CVE-2006-3632)

This update fixes several security related bugs ranging from crashes to arbitrary code execution. (CVE-2006-3627, CVE-2006-3628, CVE-2006-3629, CVE-2006-3630, CVE-2006-3631, CVE-2006-3632)

A number of vulnerabilities have been discovered in the Wireshark (formerly Ethereal) network analyzer. These issues have been corrected in Wireshark version 0.99.2 which is provided with this update.

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

  - CVE-2006-3628     Ilja van Sprundel discovered that the FW-1 and MQ     dissectors are vulnerable to format string attacks.

  - CVE-2006-3629     Ilja van Sprundel discovered that the MOUNT dissector is     vulnerable to denial of service through memory     exhaustion.

  - CVE-2006-3630     Ilja van Sprundel discovered off-by-one overflows in the     NCP NMAS and NDPS dissectors.

  - CVE-2006-3631     Ilja van Sprundel discovered a buffer overflow in the     NFS dissector.

  - CVE-2006-3632     Ilja van Sprundel discovered that the SSH dissector is     vulnerable to denial of service through an infinite     loop.

The remote host is affected by the vulnerability described in GLSA-200607-09 (Wireshark: Multiple vulnerabilities)

    Wireshark dissectors have been found vulnerable to a large number of     exploits, including off-by-one errors, buffer overflows, format string     overflows and an infinite loop.
  Impact :

    Running an affected version of Wireshark or Ethereal could allow for a     remote attacker to execute arbitrary code on the user's computer by     sending specially crafted packets.
  Workaround :

    There is no known workaround at this time.
