An issue was discovered in WibuKey64.sys in WIBU-SYSTEMS WibuKey before v6.70 and fixed in v.6.70. An improper bounds check allows crafted packets to cause an arbitrary address write, resulting in kernel memory corruption.

A heap buffer overflow vulnerability in Wibu CodeMeter Runtime network service up to version 7.60b allows an unauthenticated, remote attacker to achieve RCE and gain full access of the host system.

In WIBU CodeMeter Runtime before 7.30a, creating a crafted CmDongles symbolic link will overwrite the linked file without checking permissions.

A buffer over-read vulnerability exists in Wibu-Systems CodeMeter versions < 7.21a. An unauthenticated remote attacker can exploit this issue to disclose heap memory contents or crash the CodeMeter Runtime Server.

A denial of service vulnerability exists in Wibu-Systems CodeMeter versions < 7.21a. An unauthenticated remote attacker can exploit this issue to crash the CodeMeter Runtime Server.

Protocol encryption can be easily broken for CodeMeter (All versions prior to 6.90 are affected, including Version 6.90 or newer only if CodeMeter Runtime is running as server) and the server accepts external connections, which may allow an attacker to remotely communicate with the CodeMeter API.

CodeMeter (All versions prior to 6.90 when using CmActLicense update files with CmActLicense Firm Code) has an issue in the license-file signature checking mechanism, which allows attackers to build arbitrary license files, including forging a valid license file as if it were a valid license file of an existing vendor. Only CmActLicense update files with CmActLicense Firm Code are affected.

Multiple memory corruption vulnerabilities exist in CodeMeter (All versions prior to 7.10) where the packet parser mechanism does not verify length fields. An attacker could send specially crafted packets to exploit these vulnerabilities.

CodeMeter (All versions prior to 6.81) and the software using it may crash while processing a specifically crafted license file due to unverified length fields.
