Security Advisory Description

GNU Libtasn1 has been cited with the following vulnerabilities, which may be exploitable on some F5 products:

Multiple unspecified vulnerabilities in the DER decoder in GNU Libtasn1 before 3.6, as used in GnutTLS, allow remote attackers to cause a denial of service (out-of-bounds read) via a crafted ASN.1 data.

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.
Impact
An attacker may be able to cause a denial of service (out-of-bounds read) using crafted ASN.1 data.
