Amazon Linux 1 Security Advisory: ALAS-2020-1451
Advisory Release Date: 2020-11-14 01:23 Pacific
Advisory Updated Date: 2020-11-16 20:47 Pacific
Severity:
Medium
Issue Overview:
An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack. (CVE-2020-25613)
