RHBA-2009:0276 - Bug Fix Advisory

Topic

Updated dos2unix packages that resolve two bugs are now available.

Description

The dos2unix utility converts DOS or MAC format text files to UNIX
format.

This updated package provides fixes for the following bugs:

• dos2unix did not allow for instances where a user specified the -c

option without a conversion mode name following it. An input in this format
would therefore result in a segmentation fault. Dos2unix now exits safely
with a message to the user that option -c requires an argument.

• when dos2unix created a new file as the output of its conversion (when

run with the -n option), the new file would always have its permission mode
set as 600, regardless of the permission mode of the original file.
Dos2unix now sets the permission mode for the new file to be the same as
the mode of the old file, filtered through the user's umask.

Users of dos2unix should upgrade to this updated package, which resolves
these issues.
