Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2024-7347)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to a boundary condition within the ngx_http_mp4_module when reading mp4 files. A remote attacker can pass a specially crafted file to the web server, trigger an out-of-bounds read error and perform a denial of service (DoS) attack.

Successful exploitation of the vulnerability requires that the server is built with the ngx_http_mp4_module and the "mp4" directive is used in the configuration file.
