The remote Red Hat host is missing one or more security updates.
An update for libtasn1 is now available for Red Hat Enterprise Linux
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.
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)
