RHBA-2014:0587 - finger bug fix update
Synopsis
finger bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated finger packages that fix one bug are now available for Red Hat Enterprise Linux 6.
Description
The finger utility allows users to display information about users on the system, including their login names, full names, and the time they logged in to the system.
The update fixes the following bug:
- When the "compat" method is specified in the nsswitch.conf file, special entries containing the "+" or "-" characters are allowed to be used in the /etc/passwd file. Previously, when the finger utility was run with a "username" argument on a host that had the special entries in /etc/passwd, finger terminated with a segmentation fault. With this update, the code that handles the "username" argument has been fixed to perform the necessary checks and the finger utility no longer crashes in the described scenario. (BZ#816328)
All users of finger are advised to upgrade to these updated packages, which fix this bug.
Solution
Before applying this update, make sure all previously released errata relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258
