CVE-2013-0296: Race Condition
First published: Fri Feb 15 2013(Updated: )
Race condition in pigz before 2.2.5 uses permissions derived from the umask when compressing a file before setting that file's permissions to match those of the original file, which might allow local users to bypass intended access permissions while compression is occurring.
