CVE-2017-7700
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.
Does this matter?
Lower severity and a low EPSS score (2.10%). Track it; it rarely justifies an emergency change on its own.
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.
