Name of the Vulnerable Software and Affected Versions Wireshark versions 2.4.0 through 2.4.13 Wireshark versions 2.6.0 through 2.6.7 Wireshark version 3.0.0

Description The issue exists due to insufficient input validation in the NetScaler module of the Wireshark network traffic analyzer. This could allow a remote attacker to cause a denial of service, potentially crashing the NetScaler file parser. The problem was addressed by improving data validation in the wiretap/netscaler.c file.

Recommendations For Wireshark versions 2.4.0 through 2.4.13, update the wiretap/netscaler.c file by improving data validation to prevent the NetScaler file parser from crashing. For Wireshark versions 2.6.0 through 2.6.7, update the wiretap/netscaler.c file by improving data validation to prevent the NetScaler file parser from crashing. For Wireshark version 3.0.0, update the wiretap/netscaler.c file by improving data validation to prevent the NetScaler file parser from crashing.
