CVE-2006-6169: Gnupg

Medium severity, CVSS 6.8. EPSS: 3.3% chance of exploitation in the next 30 days.

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.

Affected products

• Gnupg Gnupg: version 1.4 only; version 2.0 only
