1.50.1. RHBA-2011:0976: gzip bug fix update
An updated gzip package that fixes two bugs is now available for Red Hat Enterprise Linux 5.
* Previously, an automatic attempt to close the standard output (stdout) stream could under certain circumstances fail. However, the gzip utility did not check if the final stdout close was successful. Due to this issue, the gzip utility could cause silent data loss while it returned a zero exit status, indicating success. This update closes the stdin and stdout streams carefully at exit time. Now, a non-zero exit status is returned if there are any problems while closing the stdin or stdout streams. (BZ#514562
Users of gzip are advised to upgrade to this updated package, which fixes these bugs.
