lrzsz before 0.13.0 contains a heap-based buffer overflow vulnerability in procheader() of the lrz receive utility when copying overlong sender-supplied filenames into Pathname. Malicious ZMODEM senders can supply filenames up to 8192 bytes, overflowing the buffer via sprintf() in pipe mode or strcpy() to corrupt heap memory and crash lrz.
