MGASA-2022-0161 - Updated lighttpd packages fix security vulnerability

Publication date: 06 May 2022
URL: https://advisories.mageia.org/MGASA-2022-0161.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2022-22707

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. (CVE-2022-22707)
