<p>The GNU Privacy Guard, GnuPG, is a free replacement for the PGP suite of
|
|
cryptographic software. The GPGSM utility in GnuPG is responsible for
|
|
processing X.509 certificates, signatures and encryption as well as
|
|
S/MIME messages.

<description>
|
|
<p>The GPGSM utility in GnuPG contains a use-after-free vulnerability that
|
|
may be exploited when importing a crafted X.509 certificate explicitly or
|
|
during the signature verification process.

<impact type="normal">
|
|
<p>An unauthenticated remote attacker may execute arbitrary code with the
|
|
privileges of the user running GnuPG by enticing them to import a crafted
|
|
certificate.

</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
