OpenSSL is a toolkit implementing the Secure Sockets Layer, Transport
|
|
Layer Security protocols and a general-purpose cryptography library.

|
Tavis Ormandy and Will Drewry, both of the Google Security Team,
|
|
discovered that the SSL_get_shared_ciphers() function contains a buffer
|
|
overflow vulnerability, and that the SSLv2 client code contains a flaw
|
|
leading to a crash. Additionally Dr. Stephen N. Henson found that the
|
|
ASN.1 handler contains two Denial of Service vulnerabilities: while
|
|
parsing an invalid ASN.1 structure and while handling certain types of
|
|
public key.
|

|
<impact type="high">
|
|
<p>
|
|
An attacker could trigger the buffer overflow vulnerability by sending
|
|
a malicious suite of ciphers to an application using the vulnerable
|
|
function, and thus execute arbitrary code with the rights of the user
|
|
running the application. An attacker could also consume CPU and/or
|
|
memory by exploiting the Denial of Service vulnerabilities. Finally a
|
|
malicious server could crash a SSLv2 client through the SSLv2
|
|
vulnerability.

<workaround>

|

There is no known workaround at this time.

All OpenSSL 0.9.8 users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8d"</code>
|
|
<p>
|
|
All OpenSSL 0.9.7 users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.7l"</code>
|
