CVE-2022-22707: Buffer Overflow
In lighttpd 1.4.46 through 1.4.63, the modextforwardForwarded function of the modextforward 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.
