I don't believe a CVE has been assigned to this, could one be? A buffer overflow was reported [1],[2] in mcrypt version 2.6.8 and earlier due to a boundary error in the processing of an encrypted file (via the check_file_head() function in src/extra.c). If a user were tricked into attempting to decrypt a specially-crafted .nc encrypted flie, this flaw would cause a stack-based buffer overflow that could potentially lead to arbitrary code execution.
