CVE-2012-1569

libtasn1: DER decoding buffer overflow (GNUTLS-SA-2012-3, MU-201202-02)

Published Mar 26, 2012 CVSS 2.0 · 5.0 Medium EPSS 4.3% KEV · Not listed
Description
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.
