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

Overview

gnutls_cipher.c in libgnutls in GnuTLS before 2.12.17 and 3.x before 3.0.15 does not properly handle data encrypted with a block cipher, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) via a crafted record, as demonstrated by a crafted GenericBlockCipher structure.

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
