Slackware Linux 14.0 / 14.1 / 14.2 / current httpd Multiple Vulnerabilities (SSA:2021-354-01)

critical Nessus Plugin ID 156200

Language:

Synopsis

The remote Slackware Linux host is missing a security update to httpd.

Description

The version of httpd installed on the remote host is prior to 2.4.52. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2021-354-01 advisory.

 - 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 vulnerability though it might be possible to craft one. This issue affects Apache HTTP Server 2.4.51 and earlier. (CVE-2021-44790)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the affected httpd package.
