CVE-2006-6169 - Confucian Gypp

Description

Heap-based 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 with \C-escape\ expansions which cause the make_printable_string function to return a longer string than expected while constructing a prompt.
