CVE-2014-3468: Debian Linux

High severity, CVSS 7.5. EPSS: 3.8% chance of exploitation in the next 30 days.

The asn1_get_bit_der function in GNU Libtasn1 before 3.6 does not properly report an error when a negative bit length is identified, which allows context-dependent attackers to cause out-of-bounds access via crafted ASN.1 data.
