Bug Fix Advisory

Topic

Updated file packages that fix various bugs are now available for Red Hat
Enterprise Linux 5.

Description

The File utility is used to identify a particular file according to the type of
data contained in the file.

This update fixes the following bugs:

• 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#486328)
  
• 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#489493)
  
• 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#494831)
  
• 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#498671)
  
• 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#504417)
  
• 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#505656)
  
• 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#508688)
  
• 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#548450)
  
• 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#618910)
  
• 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#641838)
  
• 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#668125)
  
• 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#692435)
  
• 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. (BZ#758429)
  

All users of the file utility are advised to upgrade to these updated packages,
which fix these bugs.
