critical Nessus Plugin ID 102647

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

The following packages have been upgraded to a later upstream version:
libtasn1 (4.10).

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)

Solution
