Chris Evans discovered a flaw in how LittleCms checks certain upper-bounds sizes. This flaw could potentially lead to arbitrary code execution in applications that use the system LittleCms library, or embed the source into their application. Acknowledgements: Red Hat would like to thank Chris Evans from the Google Security Team for reporting these issues.
