Alpine: multiple apache2 packages: security update to 2.4.52-r0

critical Tenable Cloud Security Plugin ID 423657

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - A crafted URI sent to httpd configured as a forward proxy (ProxyRequests on) can cause a crash (NULL
 pointer dereference) or, for configurations mixing forward and reverse proxy declarations, can allow for
 requests to be directed to a declared Unix Domain Socket endpoint (Server Side Request Forgery). This
 issue affects Apache HTTP Server 2.4.7 up to 2.4.51 (included). (CVE-2021-44224)

 - A carefully crafted request body can cause a buffer overflow in the mod_lua multipart parser
 (r:parsebody() called from Lua scripts). The Apache httpd team is not aware of an exploit for the
 vulnerabilty though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and
 earlier. (CVE-2021-44790)
