CVE-2016-4021 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:17.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream pgpdump package and not the pgpdump package as distributed by Ubuntu.
The read_binary function in buffer.c in pgpdump before 0.30 allows context-dependent attackers to cause a denial of service (infinite loop and CPU consumption) via crafted input, as demonstrated by the \xa3\x03 string.
