Base vector

AV:N/AC:M/Au:N/C:N/I:N/A:P

Name of the Vulnerable Software and Affected Versions Wireshark versions 1.6.x through 1.6.2

Description The issue is related to the csnStreamDissector function in the CSN.1 dissector, which does not initialize a certain variable. This allows remote attackers to cause a denial of service, resulting in an application crash, via a malformed packet.

Recommendations For Wireshark versions 1.6.x through 1.6.2, update to version 1.6.3 or later to resolve the issue. As a temporary workaround, consider restricting the use of the CSN.1 dissector to minimize the risk of exploitation.
