[slackware-security] httpd

New httpd packages are available for Slackware 14.0, 14.1, 14.2, and -current
to fix security issues.

Here are the details from the Slackware 14.2 ChangeLog:

patches/packages/httpd-2.4.52-i586-1_slack14.2.txz: Upgraded.
SECURITY: CVE-2021-44790: Possible buffer overflow when parsing
multipart content in mod_lua of Apache HTTP Server 2.4.51 and
earlier (cve.mitre.org)
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.

SECURITY: CVE-2021-44224: Possible NULL dereference or SSRF in
forward proxy configurations in Apache HTTP Server 2.4.51 and
earlier (cve.mitre.org)
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).
