[GLSA-200612-03] GnuPG: Multiple vulnerabilities Vulnerability Scan
Vulnerability Scan Summary
GnuPG: Multiple vulnerabilities
Detailed Explanation for this Vulnerability Test
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.

# emerge --sync
# emerge --ask --oneshot --verbose "=app-crypt/gnupg-1.4*"
Threat Level: Medium
