RHBA-2014:0297 - Bug Fix Advisory

Topic

Updated gzip packages that fix two bugs are now available for Red Hat Enterprise
Linux 6.

Description

The gzip packages provide the GNU gzip data compression program.

This update fixes the following bugs:

• Previously, the "-h" option of the zgrep command was absent from the source

code of the gzip utility. As a consequence, the output of running the "zgrep -h"
command was not parsed, and the file name was printed. With this update, the
possibility to use the short "-h" option besides the "--no-filename" option has
been added. As a result, running the zgrep command with the "-h" option now
prints the correct lines and suppresses the prefixing of the file names on
output when multiple files are searched. (BZ#949820)

• Prior to this update, the time stamp of an archive was set by the futimesat()

or utime() system calls when using the gzip utility. Consequently, the archived
file had a lower time stamp than expected because only microsecond resolution
was enabled, and a nanosecond time stamp was not provided. The underlying source
code has been modified to attempt to use the utimensat() or futimens() system
calls for nanosecond resolution. As a result, the archived file has exactly the
same time stamp as the original file. (BZ#961810)

Users of gzip are advised to upgrade to these updated packages, which fix these
bugs.

Solution

Before applying this update, make sure all previously released errata relevant
to your system have been applied.
