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.
Notes

| ebarretto | According to upstream the impact is limited to 32-bit lighttpd and to specific lighttpd mod_extforward configurations expected to be rare. |
