CVE-2015-2806 Libtasn1 vulnerability
Title: Libtasn1 vulnerability
Summary: Libtasn1 could be made to crash or run programs if it processed specially
crafted data.
Hanno Böck discovered that Libtasn1 incorrectly handled certain ASN.1 data.
A remote attacker could possibly exploit this with specially crafted ASN.1
data and cause applications using Libtasn1 to crash, resulting in a denial
of service, or possibly execute arbitrary code.
Instructions: In general, a standard system update will make all the necessary changes.

libtasn1: stack overflow in asn1_der_decoding
Stack-based buffer overflow in asn1_der_decoding in libtasn1 before 4.4 allows remote attackers to have unspecified impact via unknown vectors.
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 libtasn1: stack overflow in asn1_der_decoding
From http://lists.gnu.org/archive/html/help-libtasn1/2015-03/msg00002.html:
GNU Libtasn1 is a standalone library written in C for manipulating ASN.1
objects including DER/BER encoding/decoding. GNU Libtasn1 is used by
GnuTLS to handle X.509 structures and by GNU Shishi to handle Kerberos
V5 structures.
* Noteworthy changes in release 4.4 (released 2015-03-29) [stable]
- Corrected a two-byte stack overflow in asn1_der_decoding. Reported
by Hanno Böck.

## Abstract
How do we find new memory safety bugs effectively when navigating a symbolic execution tree that suffers from the well-known path explosion challenge?
Existing solutions either adopt path search heuristics to maximize coverage rate or chopped symbolic execution to skip uninteresting code
