The remote host is missing an update for the 'libtasn1'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
