Resumen:	The remote host is missing an update for the 'usermode, libuser' package(s) announced via the ALAS-2015-572 advisory.
Descripción:	Summary: The remote host is missing an update for the 'usermode, libuser' package(s) announced via the ALAS-2015-572 advisory. Vulnerability Insight: It was found that libuser, as used in the chfn userhelper functionality, does not properly filter out newline characters, which allows an authenticated local attacker to corrupt the /etc/passwd file and cause denial-of-service against the system. (CVE-2015-3245) A flaw was found in the way the libuser library handled the /etc/passwd file. A local attacker could use an application compiled against libuser (for example, userhelper) to manipulate the /etc/passwd file, which could result in a denial of service or possibly allow the attacker to escalate their privileges to root. (CVE-2015-3246) Affected Software/OS: 'usermode, libuser' package(s) on Amazon Linux. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
