rh#1644511

nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive memory consumption.

upstream patch:
https://hg.nginx.org/nginx/rev/d4448892a294

Comment 3 Robert Frohl 2018-11-07 14:09:00 UTC

Hi Artem,
my investigation suggests that the following codestream is affected:
- SUSE:SLE-15:Update/nginx


SLE-11-SP2 is not affected because HTTP/2 is not supported in the version we ship there.
