Title:	Ubuntu: Security Advisory (USN-2935-3)
Summary:	The remote host is missing an update for the 'pam' package(s) announced via the USN-2935-3 advisory.
Description:	Summary: The remote host is missing an update for the 'pam' package(s) announced via the USN-2935-3 advisory. Vulnerability Insight: USN-2935-1 fixed vulnerabilities in PAM. The updates contained a packaging change that prevented upgrades in certain multiarch environments. USN-2935-2 intended to fix the problem but was incomplete for Ubuntu 12.04 LTS. This update fixes the problem in Ubuntu 12.04 LTS. We apologize for the inconvenience. Original advisory details: It was discovered that the PAM pam_userdb module incorrectly used a case-insensitive method when comparing hashed passwords. A local attacker could possibly use this issue to make brute force attacks easier. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2013-7041) Sebastian Krahmer discovered that the PAM pam_timestamp module incorrectly performed filtering. A local attacker could use this issue to create arbitrary files, or possibly bypass authentication. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-2583) Sebastien Macke discovered that the PAM pam_unix module incorrectly handled large passwords. A local attacker could possibly use this issue in certain environments to enumerate usernames or cause a denial of service. (CVE-2015-3238) Affected Software/OS: 'pam' package(s) on Ubuntu 12.04. Solution: Please install the updated package(s). CVSS Score: 5.8 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:N/A:P
