Slackware Linux 15.0 / current httpd Multiple Vulnerabilities (SSA:2024-095-01)

high Nessus Plugin ID 192935

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 2.4.59. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2024-095-01 advisory.

 - Faulty input validation in the core of Apache allows malicious or exploitable backend/content generators to split HTTP responses. This issue affects Apache HTTP Server: through 2.4.58. (CVE-2023-38709)

 - HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject malicious response headers into backend applications to cause an HTTP desynchronization attack. Users are recommended to upgrade to version 2.4.59, which fixes this issue. (CVE-2024-24795)

 - HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.
 (CVE-2024-27316)

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

Solution

Upgrade the affected httpd package.
