EulerOS 2.0 SP1 : libtasn1 (EulerOS-SA-2017-1171)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote EulerOS host is missing multiple security updates.

Description :

According to the versions of the libtasn1 packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

- 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)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
