Vulnerability Summary for CVE-2012-1569

Original release date: 03/26/2012
Last revised: 03/26/2014
Source: US-CERT/NIST

Overview

The asn1_get_length_der function in decoding.c in GNU Libtasn1 before 2.12, as used in GnuTLS before 3.0.16 and other products, does not properly handle certain large length values, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) or possibly have unspecified other impact via a crafted ASN.1 structure.

Impact

CVSS Severity (version 2.0):
CVSS v2 Base Score: 5.0 (MEDIUM) (AV:N/AC:L/AU:N/C:N/I:N/A:P) (legend)
Impact Subscore: 2.9
Exploitability Subscore: 10.0
CVSS Version 2 Metrics:
Access Vector: Network exploitable
Access Complexity: Low
Authentication: Not required to exploit
Impact Type: Allows disruption of service
