critical Nessus Plugin ID 87327
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote multi-function device is affected by multiple vulnerabilities.

Description

According to its model number and software version, the remote Xerox WorkCentre 77XX device is affected by multiple vulnerabilities :

- A security feature bypass vulnerability, known as FREAK (Factoring attack on RSA-EXPORT Keys), exists due to the support of weak EXPORT_RSA cipher suites with keys less than or equal to 512 bits. A man-in-the-middle attacker may be able to downgrade the SSL/TLS connection to use EXPORT_RSA cipher suites which can be factored in a short amount of time, allowing the attacker to intercept and decrypt the traffic. (CVE-2015-0204)

- A heap-based buffer overflow condition exists in the GNU C Library (glibc) due to improper validation of user-supplied input to the glibc functions
__nss_hostname_digits_dots(), gethostbyname(), and gethostbyname2(). This allows a remote attacker to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. This vulnerability is known as GHOST. (CVE-2015-0235)

Solution

Apply the appropriate cumulative update as described in the Xerox security bulletin in the referenced URL.
