Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Buffer overflow

EUVDB-ID: #VU71241

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2006-20001

CWE-ID:

Exploit availability:

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error within the mod_dav module when handling HTTP requests. A remote attacker can send a specially crafted HTTP request, trigger a one byte buffer overflow and perform a denial of service (DoS) attack.

Mitigation

Update the affected packages.
www-servers/apache to version: 2.4.56

Vulnerable software versions

Gentoo Linux: All versions

www-servers/apache: before 2.4.56

Fixed software versions

Q & A

Can this vulnerability be exploited remotely?

Is there known malware, which exploits this vulnerability?

2) Inconsistent interpretation of HTTP requests

EUVDB-ID: #VU71242

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2022-36760

CWE-ID:

Exploit availability:

Description

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests in mod_proxy_ajp. A remote attacker can send a specially crafted HTTP request to the web server and smuggle arbitrary HTTP headers to the AJP server it forwards requests to.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

Mitigation

Update the affected packages.

3) HTTP response splitting

EUVDB-ID: #VU71243

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2022-37436

CWE-ID:

Exploit availability:

Description

The vulnerability allows a remote attacker to perform HTTP splitting attacks.

The vulnerability exists due to software does not correctly process CRLF character sequences within the mod_proxy module. A remote attacker can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.

Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.

Mitigation

Update the affected packages.
