Description

Buffer overflow in the ask_outfile_name function in openfile.c for GnuPG (gpg) 1.4 and 2.0, when running interactively, might allow attackers to execute arbitrary code via messages that cause the make_printable_string function to return a longer string than expected while constructing a prompt.

Updated packages have been patched to correct this issue.
