CentOS Errata and Security Advisory CESA-2017:1860
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)
