|
|
Moritz Jodeit reported an off-by-one error in the
|
|
SSL_get_shared_ciphers() function, resulting from an incomplete fix of
|
|
CVE-2006-3738. A flaw has also been reported in the
|
|
BN_from_montgomery() function in crypto/bn/bn_mont.c when performing
|
|
Montgomery multiplication.

<impact type="high">
|
|
<p>
|
|
A remote attacker sending a specially crafted packet to an application
|
|
relying on OpenSSL could possibly execute arbitrary code with the
|
|
privileges of the user running the application. A local attacker could
|
|
perform a side channel attack to retrieve the RSA private keys.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All OpenSSL users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8e-r3"</code>
|
|
</resolution>
