-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: glibc security, bug fix, and enhancement update Advisory ID: RHSA-2018:0805-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2018:0805 Issue date: 2018-04-10 CVE Names: CVE-2014-9402 CVE-2015-5180 CVE-2017-12132 CVE-2017-15670 CVE-2017-15804 CVE-2018-1000001 ===================================================================== 1. Summary: An update for glibc is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. 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 Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server (v. 7) - aarch64, ppc64le, s390x Red Hat Enterprise Linux for ARM and IBM Power LE (POWER9) Server Optional (v. 7) - aarch64, ppc64le, s390x 3. Description: The glibc packages provide the standard C libraries (libc), POSIX thread libraries (libpthread), standard math libraries (libm), and the name service cache daemon (nscd) used by multiple programs on the system. Without these libraries, the Linux system cannot function correctly. Security Fix(es): * glibc: realpath() buffer underflow when getcwd() returns relative path allows privilege escalation (CVE-2018-1000001) * glibc: Buffer overflow in glob with GLOB_TILDE (CVE-2017-15670) * glibc: Buffer overflow during unescaping of user names with the ~ operator (CVE-2017-15804) * glibc: denial of service in getnetbyname function (CVE-2014-9402) * glibc: DNS resolver NULL pointer dereference with crafted record type (CVE-2015-5180) * glibc: Fragmentation attacks possible when EDNS0 is enabled (CVE-2017-12132) For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section. Red Hat would like to thank halfdog for reporting CVE-2018-1000001. The CVE-2015-5180 issue was discovered by Florian Weimer (Red Hat Product Security). Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.5 Release Notes linked from the References section. 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 For the update to take effect, all services linked to the glibc library must be restarted, or the system rebooted. 5.
