RHBA-2010:0512 - Bug Fix Advisory

Topic

Updated pam packages that fix a bug are now available.

Description

Pluggable Authentication Modules (PAM) provide a system where administrators can
set up authentication policies, without having to recompile programs to handle
authentication.

These updated packages fix the following bug:

• audit messages generated by PAM contained textual descriptions of any PAM

error. The descriptions contained white space which caused the 'ausearch'
command to incorrectly parse such messages as they should not contain any white
space. The updated PAM packages generate audit messages that only report the
success or failure of the PAM call and do not contain the textual description of
a possible PAM error. Thus, 'ausearch' is able to parse them correctly.

All pam users are advised to upgrade to these updated packages, which resolve
this issue.
