Technical Description

Multiple vulnerabilities have been identified in Ruby on Rails, which could be exploited by attackers to bypass security restrictions, disclose sensitive information or cause a denial of service.

The first issue is caused by an error in the XML parser when processing specially crafted requests, which could be exploited by attackers to cause a denial of service or read the contents of arbitrary files on a vulnerable system.

The second vulnerability is caused by an error in the session management functionality that allows users to provide their "session_id" in URLs and cookies, which could be exploited to conduct session fixation attacks and gain unauthorized access.
