The Debian security team deemed this advisory irrelevant for Debian:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream lighttpd package and not the lighttpd package as distributed by Debian.
In lighttpd 1.4.46 through 1.4.63, the mod_extforward_Forwarded function of the mod_extforward plugin has a stack-based buffer overflow (4 bytes representing -1), as demonstrated by remote denial of service (daemon crash) in a non-default configuration. The non-default configuration requires handling of the Forwarded header in a somewhat unusual manner. Also, a 32-bit system is much more likely to be affected than a 64-bit system.
