[GLSA-200612-03] GnuPG: Multiple vulnerabilities

Vulnerability Assessment Summary
GnuPG: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200612-03
(GnuPG: Multiple vulnerabilities)


Hugh Warrington has reported a boundary error in GnuPG, in the
"ask_outfile_name()" function from openfile.c: the
make_printable_string() function could return a string longer than
expected. Additionally, Tavis Ormandy of the Gentoo Security Team
reported a design error in which a function pointer can be incorrectly
dereferenced.

Impact

A remote attacker could entice a user to interactively use GnuPG on a
crafted file and trigger the boundary error, which will result in a
buffer overflow. They could also entice a user to process a signed or
encrypted file with gpg or gpgv, possibly called through another
application like a mail client, to trigger the dereference error. Both
of these vulnerabilities would result in the execution of arbitrary
code with the permissions of the user running GnuPG. gpg-agent, gpgsm
and other tools are not affected.

Workaround

There is no known workaround at this time.
