The package jenkins before version 1.583-1 is vulnerable to multiple
vulnerabilities, including but not limited to:
- denial of service ;
- information leakage ;
- privilege escalation ;
- XSS ;
- arbitrary file system write ;
- remote code execution.

Resolution
==========

Upgrade to 1.583-1.

# pacman -Syu "jenkins>=1.583-1"

The problem has been fixed upstream in version 1.583.

Workaround
==========

None.

Description
===========

- SECURITY-87/CVE-2014-3661 (anonymous DoS attack through CLI handshake)
This vulnerability allows unauthenticated users with access to Jenkins'
HTTP/HTTPS port to mount a DoS attack on Jenkins through thread exhaustion.

- SECURITY-110/CVE-2014-3662 (User name discovery)
Anonymous users can test if the user of a specific name exists or not
through login attempts.

- SECURITY-127&128/CVE-2014-3663 (privilege escalation in job
configuration permission)
An user with a permission limited to Job/CONFIGURE can exploit this
vulnerability to effectively create a new job, which should have been
only possible for users with Job/CREATE permission, or to destroy jobs
that he/she does not have access otherwise.

- SECURITY-131/CVE-2014-3664 (directory traversal attack)
Users with Overall/READ permission can access arbitrary files in the
file system readable by the Jenkins process, resulting in the exposure
of sensitive information, such as encryption keys.

- SECURITY-138/CVE-2014-3680 (Password exposure in DOM)
If a parameterized job has a default value in a password field, that
default value gets exposed to users with Job/READ permission.

- SECURITY-143/CVE-2014-3681 (XSS vulnerability in Jenkins core)
Reflected cross-site scripting vulnerability in Jenkins core. An
attacker can navigate the user to a carefully crafted URL and have the
user execute unintended actions.

- SECURITY-150/CVE-2014-3666 (remote code execution from CLI)
Unauthenticated user can execute arbitrary code on Jenkins master by
sending carefully crafted packets over the CLI channel.

- SECURITY-155/CVE-2014-3667 (exposure of plugin code)
Programs that constitute plugins can be downloaded by anyone with the
Overall/READ permission, resulting in the exposure of otherwise
sensitive information, such as hard-coded keys in plugins, if any.

- SECURITY-159/CVE-2013-2186 (arbitrary file system write)
Security vulnerability in commons fileupload allows unauthenticated
attacker to upload arbitrary files to Jenkins master.

- SECURITY-149/CVE-2014-1869 (XSS vulnerabilities in ZeroClipboard)
reflective XSS vulnerability in one of the library dependencies of Jenkins.

- SECURITY-113/CVE-2014-3678 (XSS vulnerabilities in monitoring plugin)
Monitoring plugin allows an attacker to cause a victim into executing
unwanted actions on Jenkins instance.

- SECURITY-113/CVE-2014-3679 (hole in access control)
Certain pages in monitoring plugin are visible to anonymous users,
allowing them to gain information that they are not supposed to.

Impact
======

A remote, non-privileged attacker can execute arbitrary code, read and
write arbitrary files and trick valid users into doing unwanted actions.
