Overview
- 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.

Vendor comments
- Red HatRed Hat does not consider this bug to be a security flaw. In order for this flaw to be exploited, a user would be required to enter shellcode into an interactive GnuPG session. Red Hat considers this to be an unlikely scenario. Red Hat Enterprise Linux 5 contains a backported patch to address this issue.
