Blue Coat ProxySG 6.5.x Multiple OpenSSL Vulnerabilities

This script is Copyright (C) 2014 Tenable Network Security, Inc.


Synopsis :

The remote device is potentially affected by multiple vulnerabilities.

Description :

The remote Blue Coat ProxySG device's SGOS self-reported version is
6.5 prior to 6.5.4.4 and, therefore, contains a bundled version of
OpenSSL that contains multiple flaws. It is, therefore, potentially
affected by the following vulnerabilities :

- An error exists in the function 'ssl3_read_bytes'
that could allow data to be injected into other
sessions or allow denial of service attacks. Note
this issue is only exploitable if
'SSL_MODE_RELEASE_BUFFERS' is enabled. (CVE-2010-5298)

- An error exists in the function 'do_ssl3_write' that
could allow a NULL pointer to be dereferenced leading
to denial of service attacks. Note this issue is
exploitable only if 'SSL_MODE_RELEASE_BUFFERS' is
enabled. (CVE-2014-0198)

- An unspecified error exists that could allow an
attacker to cause usage of weak keying material,
leading to simplified man-in-the-middle attacks.
(CVE-2014-0224)
