RHBA-2012:1029 - file bug fix update

Synopsis

file bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated file packages that fix multiple 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:

  • Prior to this update, the swap signature on the Itanium architecture was not stored in the same place as on other architectures. As a consequence, the file utility failed to detect the swap signature on Itanium. This update adds a new "magic" pattern to detect the swap signature on Itanium architecture. (BZ#758105)

  • Prior to this update, the "magic" pattern to detect Infocom Game Data was too weak. As a consequence, Some files were wrongly identified as Infocom Game Data when they were actually in different format. This update modifies the Infocom Game Data "magic" pattern so only valid Infocom Game Data files are detected by this pattern. (BZ#789830)

  • Prior to this update, the file utility did not contain a "magic" pattern to detect zip64 (zip 3.0) files. As a consequence, the file utility failed to detect archives in the zip64 format. This update adds a new "magic" pattern to detect the zip64 format. (BZ#758631)

  • Prior to this update, the file utility did not contain a "magic" pattern to detect WebM video files. As a consequence, the file utility failed to detect WebM video files. This update adds a new "magic" pattern to detect the WebM files. (BZ#758634)

  • Prior to this update, the file utility did not contain a "magic" pattern to detect LZMA archives. As a consequence, the file utility failed to detect archives in LZMA format were not detected. This update adds a new "magic" pattern to detect the LZMA files. (BZ#809801)

  • Prior to this update, the "magic" pattern to detect Dell BIOS headers was outdated. As a consequence, the file utility failed to detect newer BIOS formats. This update modifies the ""magic"" pattern to detect also new formats of Dell BIOS correctly. (BZ#826899)

  • Prior to this update, the file utility contained ""magic"" patterns that incorrectly detected files according to one byte only. As a consequence, Unicode text files that contained the particular byte in a particular position could be incorrectly recognized as DOS executable files. This update removes the problematic patterns. Patterns that match less than 16 bits are no longer accepted, and the utility no longer detects Unicode files as DOS executables. (BZ#826901)

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