RHBA-2014:0641 - Bug Fix Advisory

Topic

An updated perl-Authen-SASL package that fixes one bug is now available for Red
Hat Enterprise Linux 6.

Description

Simple Authentication and Security Layer (SASL) is a generic mechanism for
authentication used by several network protocols. The Authen::SASL module
provides an implementation framework that all protocols should be able to share.

This update fixes the following bug:

• Due to a bug in the Authen::SASL Perl module, the substr() function attempted

to read data outside of the appropriate string. As a consequence, when the user
was authenticated against an LDAP server over SASL, performing logical
operations, such as search, with a Perl program on that server failed. With this
update, the Authen::SASL module verifies the length of the string that is
encrypted and written to a filehandle. As a result, performing a search returns
correct results in the described situation. (BZ#965739)

Users of perl-Authen-SASL are advised to upgrade to this updated package, which
fixes this bug.
