Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Resource exhaustion

EUVDB-ID: #VU81728

Risk: High

CVSSv4.0: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:A/U:Amber]

CVE-ID: CVE-2023-44487

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: Yes

Description

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

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

Note, the vulnerability is being actively exploited in the wild.

Mitigation

Update the affected package nginx to the latest version.

2) Out-of-bounds read

EUVDB-ID: #VU96020

Risk: Medium

CVSSv4.0: 4.6 [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]

CVE-ID: CVE-2024-7347

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

Exploit availability: No

Description

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.

Mitigation

Update the affected package nginx to the latest version.
