Name of the Vulnerable Software and Affected Versions Wireshark versions 1.0.x, 1.2.0 through 1.2.14, 1.4.0 through 1.4.3

Description The issue allows remote attackers to cause a denial of service, specifically memory consumption, via certain LDAP filter strings. This can be achieved by using either a long LDAP filter string or an LDAP filter string containing many elements.

Recommendations For Wireshark versions 1.0.x, consider updating to a version outside of the affected range to resolve the issue. For Wireshark versions 1.2.0 through 1.2.14, consider updating to a version outside of the affected range to resolve the issue. For Wireshark versions 1.4.0 through 1.4.3, consider updating to a version outside of the affected range to resolve the issue. As a temporary workaround, consider restricting the use of long or complex LDAP filter strings to minimize the risk of exploitation.
