manages ASN1 (Abstract Syntax Notation One) structures. An attacker
could use those to cause a denial of service via out-of-bounds access
or NULL pointer dereference.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
