Amazon Linux 2 Security Advisory: ALAS-2019-1259
Advisory Release Date: 2019-08-07 23:48 Pacific
Advisory Updated Date: 2019-08-09 13:30 Pacific
Severity: Important

Issue Overview:

A security regression of CVE-2019-9636 was discovered in python, which still allows an attacker to exploit CVE-2019-9636 by abusing the user and password parts of a URL. When an application parses user-supplied URLs to store cookies, authentication credentials, or other kind of information, it is possible for an attacker to provide specially crafted URLs to make the application locate host-related information (e.g. cookies, authentication data) and send them to a different host than where it should, unlike if the URLs had been correctly parsed. The result of an attack may vary based on the application. (CVE-2019-10160)
