Test ID:1.3.6.1.4.1.25623.1.0.114147
Category:Web Servers
Title:Apache HTTP Server 2.4.20 - 2.4.39 Multiple Vulnerabilities (Linux)
Summary:Apache HTTP Server is prone to multiple vulnerabilities.
Description:Summary:
Apache HTTP Server is prone to multiple vulnerabilities.

Vulnerability Insight:
Apache HTTP server is prone to multiple vulnerabilities:

- A malicious client could perform a DoS attack by flooding a connection with requests and
basically never reading responses on the TCP connection. Depending on h2 worker dimensioning,
it was possible to block those with relatively few connections. (CVE-2019-9517)

- HTTP/2 very early pushes, for example configured with 'H2PushResource', could lead to
an overwrite of memory in the pushing request's pool, leading to crashes. The memory
copied is that of the configured push link header values, not data supplied by
the client. (CVE-2019-10081)

Affected Software/OS:
Apache HTTP Server version 2.4.20 to 2.4.39.

Solution:
Update to version 2.4.41 or later.

CVSS Score:
7.8
