Amazon Linux 2022 Security Advisory: ALAS-2022-018
Advisory Release Date: 2022-01-29 00:35 Pacific
Advisory Updated Date: 2022-02-03 18:40 Pacific
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)
Affected Packages:
httpd
Issue Correction:
Run dnf update --releasever=2022.0.20220202 httpd to update your system.
