CVE-2022-22707 (GCVE-0-2022-22707)

Vulnerability from cvelistv5 – Published: 2022-01-06 05:55 – Updated: 2024-08-03 03:21

Summary

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.

Severity ?
