===================================================================== Red Hat Security Advisory
Synopsis: Moderate: libtasn1 security, bug fix, and enhancement update Advisory ID: RHSA-2017:1860-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:1860 Issue date: 2017-08-01 CVE Names: CVE-2015-2806 CVE-2015-3622 =====================================================================
1. Summary:
An update for libtasn1 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) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64
3. Description:
Libtasn1 is a library that provides Abstract Syntax Notation One (ASN.1, as specified by the X.680 ITU-T recommendation) parsing and structures management, and Distinguished Encoding Rules (DER, as per X.690) encoding and decoding functions.
The following packages have been upgraded to a later upstream version: libtasn1 (4.10). (BZ#1360639)
Security Fix(es):
* A heap-based buffer overflow flaw was found in the way the libtasn1 library decoded certain DER-encoded inputs. A specially crafted DER-encoded input could cause an application using libtasn1 to perform an invalid read, causing the application to crash. (CVE-2015-3622)
* A stack-based buffer overflow was found in the way libtasn1 decoded certain DER encoded data. An attacker could use this flaw to crash an application using the libtasn1 library. (CVE-2015-2806)
Additional Changes:
For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.4 Release Notes linked from the References section.
