Descriptions

Jenkins before 1.650 and LTS before 1.642.2 do not use a constant-time algorithm to verify CSRF tokens, which makes it easier for remote attackers to bypass a CSRF protection mechanism via a brute-force approach.

Jenkins en versiones anteriores a 1.650 y LTS en versiones anteriores a 1.642.2 no utiliza un algoritmo de tiempo constante para verificar tokens CSRF, lo que hace más fácil para atacantes remotos eludir el mecanismo de protección CSRF a través de una aproximación por fuerza bruta.

OpenShift Enterprise by Red Hat is the company's cloud computing Platform- as-a-Service solution designed for on-premise or private cloud deployments. Jenkins is a continuous integration server that monitors executions of repeated jobs, such as building a software project or jobs run by cron. Security Fix: The Jenkins continuous integration server has been updated to upstream version 1.642.2 LTS that addresses a large number of security issues, including XSS, CSRF, information disclosure, and code execution.
