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

critical Nessus Plugin ID 103009

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.

Solution

Update the affected libtasn1 packages.
