Name of the Vulnerable Software and Affected Versions GNU Libtasn1 versions prior to 4.13

Description The issue is related to a NULL pointer dereference and crash in the asn1 check identifier function when reading crafted input. This may lead to a remote denial of service attack. The vulnerability is caused by errors in pointer dereferencing, specifically the lack of checking for a NULL value when reading the input stream.
