Important: httpd

Description

**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) **Affected Packages:** httpd **Issue Correction:** Run _yum update httpd_ to update your system. **New Packages:** aarch64:     httpd-2.4.52-1.amzn2.aarch64     httpd-devel-2.4.52-1.amzn2.aarch64     httpd-tools-2.4.52-1.amzn2.aarch64     mod_ssl-2.4.52-1.amzn2.aarch64     mod_md-2.4.52-1.amzn2.aarch64     mod_proxy_html-2.4.52-1.amzn2.aarch64     mod_ldap-2.4.52-1.amzn2.aarch64     mod_session-2.4.52-1.amzn2.aarch64     httpd-debuginfo-2.4.52-1.amzn2.aarch64 i686:     httpd-2.4.52-1.amzn2.i686     httpd-devel-2.4.52-1.amzn2.i686     httpd-tools-2.4.52-1.amzn2.i686     mod_ssl-2.4.52-1.amzn2.i686     mod_md-2.4.52-1.amzn2.i686     mod_proxy_html-2.4.52-1.amzn2.i686     mod_ldap-2.4.52-1.amzn2.i686     mod_session-2.4.52-1.amzn2.i686     httpd-debuginfo-2.4.52-1.amzn2.i686 noarch:     httpd-manual-2.4.52-1.amzn2.noarch     httpd-filesystem-2.4.52-1.amzn2.noarch src:     httpd-2.4.52-1.amzn2.src x86_64:     httpd-2.4.52-1.amzn2.x86_64     httpd-devel-2.4.52-1.amzn2.x86_64     httpd-tools-2.4.52-1.amzn2.x86_64     mod_ssl-2.4.52-1.amzn2.x86_64     mod_md-2.4.52-1.amzn2.x86_64     mod_proxy_html-2.4.52-1.amzn2.x86_64     mod_ldap-2.4.52-1.amzn2.x86_64     mod_session-2.4.52-1.amzn2.x86_64     httpd-debuginfo-2.4.52-1.amzn2.x86_64
