Description: A vulnerability was reported in gnuTLS. A remote user can cause denial of service conditions.
The gnuTLS libtasn1 component does not properly decode DER encoded data. A remote user can send a specially crafted X.509 certificate
that, when parsed by an application using gnuTLS, may trigger an out-of-bounds memory access error. This may cause the application
to crash.
The report indicates that it is not certain if this vulnerability will allow arbitrary code execution.
