Title:	CentOS Update for pam CESA-2015:1640 centos7
Summary:	Check the version of pam
Description:	Summary: Check the version of pam Vulnerability Insight: Pluggable Authentication Modules (PAM) provide a system whereby administrators can set up authentication policies without having to recompile programs to handle authentication. It was discovered that the _unix_run_helper_binary() function of PAM's unix_pam module could write to a blocking pipe, possibly causing the function to become unresponsive. An attacker able to supply large passwords to the unix_pam module could use this flaw to enumerate valid user accounts, or cause a denial of service on the system. (CVE-2015-3238) Red Hat would like to thank Sebastien Macke of Trustwave SpiderLabs for reporting this issue. All pam users are advised to upgrade to this updated package, which contains a backported patch to correct this issue. Affected Software/OS: pam on CentOS 7 Solution: Please install the updated packages. CVSS Score: 5.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:N/A:P
