Blue Coat ProxySG 6.5.x Multiple OpenSSL Vulnerabilities

Medium Nessus Plugin ID 76165

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)

Solution

Upgrade to version 6.5.4.4 or later.
