-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: freeradius security update Advisory ID: RHSA-2017:1759-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:1759 Issue date: 2017-07-18 CVE Names: CVE-2017-10978 CVE-2017-10979 CVE-2017-10980 CVE-2017-10981 CVE-2017-10982 CVE-2017-10983 ===================================================================== 1. Summary: An update for freeradius is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: FreeRADIUS is a high-performance and highly configurable free Remote Authentication Dial In User Service (RADIUS) server, designed to allow centralized authentication and authorization for a network. Security Fix(es): * An out-of-bounds write flaw was found in the way FreeRADIUS server handled certain attributes in request packets. A remote attacker could use this flaw to crash the FreeRADIUS server or to execute arbitrary code in the context of the FreeRADIUS server process by sending a specially crafted request packet. (CVE-2017-10979) * An out-of-bounds read and write flaw was found in the way FreeRADIUS server handled RADIUS packets. A remote attacker could use this flaw to crash the FreeRADIUS server by sending a specially crafted RADIUS packet. (CVE-2017-10978) * Multiple memory leak flaws were found in the way FreeRADIUS server handled decoding of DHCP packets. A remote attacker could use these flaws to cause the FreeRADIUS server to consume an increasing amount of memory resources over time, possibly leading to a crash due to memory exhaustion, by sending specially crafted DHCP packets. (CVE-2017-10980, CVE-2017-10981) * Multiple out-of-bounds read flaws were found in the way FreeRADIUS server handled decoding of DHCP packets. A remote attacker could use these flaws to crash the FreeRADIUS server by sending a specially crafted DHCP request. (CVE-2017-10982, CVE-2017-10983) Red Hat would like to thank the FreeRADIUS project for reporting these issues. Upstream acknowledges Guido Vranken as the original reporter of these issues. 4.
