Package : lighttpd
CVE ID : CVE-2022-37797 CVE-2022-41556
Several vulnerabilities were discovered in lighttpd, a fast webserver
with minimal memory footprint.
CVE-2022-37797
An invalid HTTP request (websocket handshake) may cause a NULL
pointer dereference in the wstunnel module.
CVE-2022-41556
A resource leak in mod_fastcgi and mod_scgi could lead to a denial
of service after a large number of bad HTTP requests.
