Unspecified vulnerability in the LDAP dissector in Wireshark (formerly Ethereal) 0.99.3 allows remote attackers to cause a denial of service (crash) via a crafted LDAP packet.

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)

Various problems have been fixed in the network analyzer Ethereal, most leading to crashes of the ethereal program.

  - A unspecified vulnerability in the LDAP dissector could     be used to crash Ethereal. (CVE-2006-5740)

  - A single \0 byte heap overflow was fixed in the MIME     multipart dissector. Potential of exploitability is     unknown, but considered low. (CVE-2006-4574)

  - A denial of service problem in the XOT dissector can     cause it to take up huge amount of memory and crash     ethereal. (CVE-2006-4805)

  - The WBXML dissector could be used to crash ethereal.
    (CVE-2006-5469)

  - A NULL pointer dereference in the HTTP dissector could     crash ethereal. (CVE-2006-5468)

Various problems have been fixed in the network analyzer Ethereal, most leading to crashes of the ethereal program.

CVE-2006-5740: A unspecified vulnerability in the LDAP dissector could be used to crash Ethereal.

CVE-2006-4574: A single \0 byte heap overflow was fixed in the MIME multipart dissector. Potential of exploitability is unknown, but considered low.

CVE-2006-4805: A denial of service problem in the XOT dissector can cause it to take up huge amount of memory and crash ethereal.

CVE-2006-5469: The WBXML dissector could be used to crash ethereal.

CVE-2006-5468: A NULL pointer dereference in the HTTP dissector could crash ethereal.

Vulnerabilities in the HTTP, LDAP, XOT, WBXML, and MIME Multipart dissectors were discovered in versions of wireshark less than 0.99.4, as well as various other bugs.

This updated provides wireshark 0.99.4 which is not vulnerable to these issues.
