Topic

Updated shadow-utils packages that fix a bug in pwconv are now available for Red
Hat Enterprise Linux 5.

Description

The shadow-utils package includes the necessary programs for converting
UNIX password files to the shadow password format, plus programs for
managing user and group accounts. The pwconv command converts passwords to
the shadow password format. The pwunconv command converts shadow passwords
and generates an npasswd file (a standard UNIX password file). The pwck
command checks the integrity of password and shadow files. The lastlog
command prints out the last login times for all users. The useradd,
userdel, and usermod commands are used for managing user accounts. The
groupadd, groupdel, and groupmod commands are used for managing group
accounts.

This update addresses the following bug in pwconv (or grpconv):

  • A structural bug in a delete routine meant /etc/shadow (or /etc/gshadow)

files containing bad entries were not updated properly by pwconv (or
grpconv). Specifically if /etc/shadow (or /etc/gshadow) contained two
consecutive bad entries, the second of the two bad entries was skipped when
pwconv (or grpconv) was run on the file. This left the file improperly
updated. With this update, the loop that iterates through /etc/shadow (or
/etc/gshadow) was reworked. No bad lines (consecutive or otherwise) are now
skipped and /etc/shadow (or /etc/gshadow) files are properly updated by
pwconv (or grpconv). (BZ#787736)

All shadow-utils users should install this update which fixes this bug.

Solution

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