high Nessus Plugin ID 202488

Language:

Synopsis

The remote Red Hat 9 host is affected by multiple vulnerabilities that will not be patched.

Description

The remote Redhat Enterprise Linux 9 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

 - ALPACA: Application Layer Protocol Confusion - Analyzing and Mitigating Cracks in TLS Authentication (CVE-2021-3618)

 - nginx: Memory corruption in the ngx_http_mp4_module (CVE-2022-41741)

 - NGINX Open Source before versions 1.23.2 and 1.22.1, NGINX Open Source Subscription before versions R2 P1 and R1 P1, and NGINX Plus before versions R27 P1 and R26 P1 have a vulnerability in the module ngx_http_mp4_module that might allow a local attacker to cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted audio or video file. The issue affects only NGINX products that are built with the module ngx_http_mp4_module, when the mp4 directive is used in the configuration file. Further, the attack is possible only if an attacker can trigger processing of a specially crafted audio or video file with the module ngx_http_mp4_module. (CVE-2022-41742)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

Solution

The vendor has acknowledged the vulnerabilities but no solution has been provided. Refer to the vendor for remediation guidance.
