| Doc Text: |
A flaw was found in lrzsz. When operating in pipe mode, the lrz receive utility does not properly sanitize file names received during file transfers before passing them to the system shell. A remote attacker can exploit this flaw by sending a specially crafted file name, leading to arbitrary command execution with the permissions of the receiving user.
