GNU Libtasn1-4.13 libtasn1-4.13 version libtasn1-4.13, libtasn1-4.12
contains a DoS, specifically CPU usage will reach 100% when running
asn1Paser against the POC due to an issue in
_asn1_expand_object_id(p_tree), after a long time, the program will be
killed. This attack appears to be exploitable via parsing a crafted file.
