nghttp2 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS (Available with Ubuntu Pro)
- Ubuntu 16.04 LTS (Available with Ubuntu Pro)


nghttp2 could be made to crash if it opened a specially crafted file.

Software Description:
- nghttp2: HTTP/2 C Library and tools


Gal Goldshtein discovered that nghttp2 incorrectly handled certain inputs. If
a user or an automated system were tricked into opening a specially crafted
input file, a remote attacker could possibly use this issue to cause a
denial of service.
