tag_summary = "nginx is prone to a buffer-overflow vulnerability because it fails to
perform adequate boundary checks on user-supplied data.

Attackers may leverage this issue to execute arbitrary code in the
context of the application. Failed attacks will cause denial-of-
service conditions.

nginx versions 1.1.3 through 1.1.18 and 1.0.7 through 1.0.14 are
vulnerable; other versions may also be affected.";
