Detail
Synopsis Multiple vulnerabilities have been found in Linux-PAM, allowing local attackers to possibly gain escalated privileges, cause a Denial of Service, corrupt data, or obtain sensitive information. Background Description Impact Workaround Resolution NOTE: This is a legacy GLSA. Updates for all affected architectures are available since November 25, 2011. It is likely that your system is already no longer affected by this issue. References Availability http://security.gentoo.org/glsa/glsa-201206-31.xml |

Title: | USN-1140-2 -- pam regression | ||
Description: | pam: Pluggable Authentication Modules Details: USN-1140-1 fixed vulnerabilities in PAM. A regression was found that caused cron to stop working with a "Module is unknown" error. As a result, systems configured with automatic updates will not receive updates until cron is restarted, these updates are installed or the system is rebooted. This update fixes the problem. We apologize for the inconvenience. Original advisory The USN-1140-1 PAM update caused cron to stop working. | ||
