Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Resource exhaustion

EUVDB-ID: #VU20196

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-9511

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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

The vulnerability exists due to improper input validation when processing HTTP/2 requests. A remote attacker can send a specially crafted HTTP/2 request the affected server, consume all available CPU resources and perform a denial of service (DoS) attack.

Successful exploitation of the vulnerability requires that support for HTTP/2 is enabled.

Mitigation

Update nodejs package to version 10.19.0~dfsg1-1.

Vulnerable software versions

nodejs (Debian package): 10.0.0~dfsg-1 - 10.17.0~dfsg-2
