Red Hat Security Advisory 2017-1860-01 - Libtasn1 is a library that provides Abstract Syntax Notation One parsing and structures management, and Distinguished Encoding Rules encoding and decoding functions. The following packages have been upgraded to a later upstream version: libtasn1. Security Fix: 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.

A specially crafted DER-encoded input could cause an application using the Libtasn1 library to crash, or potentially to execute arbitrary code.

A remote attacker could possibly exploit this with specially crafted ASN.1 data and cause applications using Libtasn1 to crash, resulting in a denial of service, or possibly execute arbitrary code.
