CVE-2017-6014 (opens in a new tab)How to fix?
Upgrade Alpine:3.12 wireshark to version 2.2.4-r1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream wireshark package and not the wireshark package as distributed by Alpine.
See How to fix? for Alpine:3.12 relevant fixed versions and status.
In Wireshark 2.2.4 and earlier, a crafted or malformed STANAG 4607 capture file will cause an infinite loop and memory exhaustion. If the packet size field in a packet header is null, the offset to read from will not advance, causing continuous attempts to read the same zero length packet. This will quickly exhaust all system memory.
