CVE-2014-7815: Input Validation

First published: Mon Oct 27 2014(Updated: )

bits_per_pixel that are less than 8 could result in accessing non-initialized buffers later in the code due to the expectation that bytes_per_pixel value that is used to initialize these buffers is never zero. An attacker having access to the guest's VNC console could use this flaw to crash the guest. Acknowledgements: Red Hat would like to thank James Spadaro of Cisco for reporting this issue.
