<title>GnuPG: Multiple vulnerabilities</title>
|
|
<synopsis>
|
|
GnuPG is vulnerable to a buffer overflow and an erroneous function pointer
|
|
dereference that can result in the execution of arbitrary code.

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 type="normal">
|
|
<p>
|
|
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>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All GnuPG users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose "=app-crypt/gnupg-1.4*"</code>
