Description Andrej Nemec 2016-02-25 08:08:10 EST
The BER decoder would crash due to reading from offset 0 of an empty vector if it encountered a BIT STRING which did not contain any data at all. This can be used to easily crash applicatons reading untrusted ASN.1 data, but does not seem exploitable for code execution.
