Important: httpd24

Issue Overview:

There’s a null pointer dereference and server-side request forgery flaw in httpd’s mod_proxy module, when it is configured to be used as a forward proxy. A crafted packet could be sent on the adjacent network to the forward proxy that could cause a crash, or potentially SSRF via misdirected Unix Domain Socket requests. In the worst case, this could cause a denial of service or compromise to confidentiality of data. (CVE-2021-44224)

A buffer overflow flaw in httpd’s lua module could allow an out-of-bounds write. An attacker who is able to submit a crafted request to an httpd instance that is using the lua module may be able to cause an impact to confidentiality, integrity, and/or availability. (CVE-2021-44790)
