| Description: | Summary:
The remote host is missing an update for the Debian 'apache2' package(s) announced via the DLA-3351-1 advisory.
Vulnerability Insight:
Multiple security vulnerabilities have been discovered in Apache HTTP server.
CVE-2006-20001
A carefully crafted If: request header can cause a memory read, or write of a single zero byte, in a pool (heap) memory location beyond the header value sent. This could cause the process to crash.
CVE-2021-33193
A crafted method sent through HTTP/2 will bypass validation and be forwarded by mod_proxy, which can lead to request splitting or cache poisoning.
CVE-2022-36760
Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling') vulnerability in mod_proxy_ajp of Apache HTTP Server allows an attacker to smuggle requests to the AJP server it forwards requests to.
CVE-2022-37436
A malicious backend can cause the response headers to be truncated early, resulting in some headers being incorporated into the response body. If the later headers have any security purpose, they will not be interpreted by the client.
For Debian 10 buster, these problems have been fixed in version 2.4.38-3+deb10u9.
We recommend that you upgrade your apache2 packages.
