CVE-2017-7700

MEDIUM
New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

In Wireshark 2.2.0 to 2.2.5 and 2.0.0 to 2.0.11, the NetScaler file parser could go into an infinite loop, triggered by a malformed capture file. This was addressed in wiretap/netscaler.c by ensuring a nonzero record size.
