Updated file packages that fix various bugs are now available for Red Hat Enterprise Linux 5.
The File utility is used to identify a particular file according to the type of data contained in the file.

Bug Fixes

BZ#486328
Previously, the file utility always checked a section of the core file which was only used by FreeBSD when looking up command names. As a consequence, an incorrect command name could be reported. This update checks this offset only if the core file was generated on a FreeBSD plattfrom. Now, the file utility displays the correct file name.
BZ#489493
Previously, the file utility did not correctly recognize file system dumps generated by the "dump" utility on PowerPC and IBM System z platforms which were wrongly identified as a "JVT NAL" sequence. This update modifies the order of the magic patterns. Now, the file utility correctly identifies these dumps.
BZ#494831
Previously, the Note field stored in Executable and Linkable Format (ELF) binaries was wrongly processed twice. As a consequence, the message "for GNU/Linux X.Y.Z" was displayed twice for certain binary files. This update modifies the process. Now, the Note field is processed only once.
BZ#498671
Previously, the definition for the Multipurpose Internet Mail Extensions (MIME) type "XML" was missing in the magic file. As a consequence, the MIME type for XML files was not displayed. This update adds this MIME type to the magic file.
BZ#504417
Previously, the file utility did not recognize the swap file system on PowerPC platforms. Now, a new magic pattern for swap on PowerPC platforms is added and the file utility now identifies the swapspace correctly.
BZ#505656
Previously, the "msword" MIME type was listed two times in DOC/XLS magic patterns. As a consequence, the "application/msword" MIME type was displayed twice for certain Microsoft Office 2007 files. Now, the second MIME type definition is removed.
BZ#508688
Previously, the magic pattern for detecting the PPD files did not work as expected. As a consequence, the file utility truncated the "version" string of certain PPD files. This update displays the "version" string correctly and no longer truncates the version number.
BZ#548450
Previously, the manual page did not mention that a 0 exit code was returned when input files were not found. This update adds the missing information to the manual page.
BZ#618910
Previously, the file utility always attempted to read complete files from stdin to get additional information about ELF binary even when the file was not an ELF binary. As a consequence, the process used a large amount of memory and took a long time. This update detects if a file is an ELF binary using the ELF magic bytes and reads the complete file only when the file is an ELF binary.
BZ#641838
Previously, the file utility could wrongly recognize gzip files as FLC files. This update changes the order of gzip and FLC magic patterns. Now, the file utility identifies gzip files correctly.
BZ#668125
Previously, the GFS1 and GFS2 file systems shared the same magic number in the superblock which the file utility used to identify the GFS2 file system. As a consequence, the file utility wrongly recognized GFS2 file systems as GFS1 file systems. This update adds a new magic pattern for the GFS2 file system. Now, the file utility identifies GFS2 correctly.
BZ#692435
Previously, two magic patterns for XML identification were wrongly merged into one. As a consequence, the file utility could not identify the MIME type for XML files starting with "?xml". This update splits these two patterns. Now, the correct MIME type is displayed.
BZ#758429
Previously, the file utility could wrongly recognize JPEG files as Minix file systems. This update changes the order of JPEG and Minix magic patterns. Now the file utility recognizes JPEG files correctly.
All users of the file utility are advised to upgrade to these updated packages, which fix these bugs.
