Описание
cpdb-libs provides frontend and backend libraries for the Common Printing Dialog Backends (CPDB) project. In versions 1.0 through 2.0b4, cpdb-libs is vulnerable to buffer overflows via improper use of scanf(3). cpdb-libs uses the fscanf() and scanf() functions to parse command lines and configuration files, dropping the read string components into fixed-length buffers, but does not limit the length of the strings to be read by fscanf() and scanf() causing buffer overflows when a string is longer than 1023 characters. A patch for this issue is available at commit f181bd1f14757c2ae0f17cc76dc20421a40f30b7. As all buffers have a length of 1024 characters, the patch limits the maximum string length to be read to 1023 by replacing all occurrences of %s with %1023s in all calls of the fscanf() and scanf() functions.
