Debian LTS Advisory DLA-3351-1 [email protected]
https://www.debian.org/lts/security/ Lee Garrett
March 03, 2023 https://wiki.debian.org/LTS
Package : apache2
Version : 2.4.38-3+deb10u9
CVE ID : CVE-2006-20001 CVE-2021-33193 CVE-2022-36760
CVE-2022-37436
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.
For the detailed security status of apache2 please refer to
its security tracker page at:
