cpdb-libs vulnerable to buffer overflows via scanf

CVE-2023-34095

What is CVE-2023-34095?

The cpdb-libs library for Common Printing Dialog Backends contains a buffer overflow vulnerability due to improper handling of input strings in scanf and fscanf functions. Boundless input lengths can lead to overruns, making it crucial to restrict maximum read lengths to prevent exploitation. A patch has been implemented to cap string lengths to 1023 characters, thus safeguarding fixed-length buffers. Users should upgrade to the latest version to mitigate this risk and ensure secure operations.
