RHBA-2012:0456 - Bug Fix Advisory

Topic

An updated expect package that fixes multiple bugs is now available for Red Hat
Enterprise Linux 6.

Description

The "expect" package contains a tool for automating and testing interactive
command line programs and Tk applications. Tcl is a portable and widely used
scripting language, while Tk is a graphical toolkit that eases development of
text-based and GUI applications.

This update fixes the following bugs:

• Prior to this update, the expect(1) manual page was not formatted properly. As

a result, the content of the manual page was not readable. The formatting has
been corrected to ensure easy readability. (BZ#674866)

• Prior to this update, the passmass script did not call the "su" binary with

the full path (/bin/su). The passmass script has been modified to call "/bin/su"
rather than "su", which is more secure. (BZ#735962)

• Due to incorrect characters matching, applications created by the autoexpect

utility could terminate unexpectedly with a segmentation fault. With this
update, the number of characters is matched correctly and applications created
by autoexpect run successfully. (BZ#742911)

• Previously, the expect-devel subpackage contained a symbolic link to the

expect library, which led to an unnecessary dependency. With this update, the
link is located in the expect package. (BZ#782859)

All users of expect are advised to upgrade to this updated package, which fixes
these bugs.
