Title:	Jenkins Multiple Vulnerabilities (Feb 2016) - Linux
Summary:	Jenkins is prone to multiple vulnerabilities.
Description:	Summary: Jenkins is prone to multiple vulnerabilities. Vulnerability Insight: Multiple flaws are due to: - The verification of user-provided API tokens with the expected value did not use a constant-time comparison algorithm, potentially allowing attackers to use statistical methods to determine valid API tokens using brute-force methods. - The verification of user-provided CSRF crumbs with the expected value did not use a constant-time comparison algorithm, potentially allowing attackers to use statistical methods to determine valid CSRF crumbs using brute-force methods. - The Jenkins has several API endpoints that allow low-privilege users to POST XML files that then get deserialized by Jenkins. Maliciously crafted XML files sent to these API endpoints could result in arbitrary code execution. - An HTTP response splitting vulnerability in the CLI command documentation allowed attackers to craft Jenkins URLs that serve malicious content. - The Jenkins remoting module allowed unauthenticated remote attackers to open a JRMP listener on the server hosting the Jenkins master process, which allowed arbitrary code execution. Vulnerability Impact: Successful exploitation will allow remote attackers to obtain sensitive information, bypass the protection mechanism, gain elevated privileges, bypass intended access restrictions and execute arbitrary code. Affected Software/OS: Jenkins main line 1.649 and prior, Jenkins LTS 1.642.1 and prior. Solution: Jenkins main line users should update to 1.650, Jenkins LTS users should update to 1.642.2.
