The processutils.execute function in OpenStack oslo-incubator, Cinder, Nova, and Trove before 2013.2.4 and 2014.1 before 2014.1.3 allows local users to obtain passwords from commands that cause a ProcessExecutionError by reading the log.

Duncan Thomas discovered that OpenStack Cinder did not properly track the file format when using the GlusterFS of Smbfs drivers. A remote authenticated user could exploit this to potentially obtain file contents from the compute host. (CVE-2014-3641)

Amrith Kumar discovered that OpenStack Cinder did not properly sanitize log message contents. Under certain circumstances, a local attacker with read access to Cinder log files could obtain access to sensitive information. (CVE-2014-7230)

Garth Mollett discovered that OpenStack Nova did not properly clean up an instance when using rescue mode with the VMWare driver. A remove authenticated user could exploit this to bypass intended quota limits. By default, Ubuntu does not use the VMWare driver. (CVE-2014-3608)

Amrith Kumar discovered that OpenStack Nova did not properly sanitize log message contents. Under certain circumstances, a local attacker with read access to Nova log files could obtain access to sensitive information. (CVE-2014-7230)
