IMPACT

        Blue Coat has provided the following details regarding the 
        vulnerability:
        
        CVE-2015-0235: "A buffer overflow exists in the GNU C Library 
        (glibc) that allows a remote attacker to execute arbitrary code 
        using the permissions of the application. A remote attacker could 
        use this vulnerability to gain administrator or root access to Blue
        Coat products using affected versions of glibc". [1]


MITIGATION

        Blue Coat advises that no patches are currently available for 
        affected products.
        
        Users of Blue Coat products running glibc are advised to:
        
           1. upgrade products to versions which are not vulnerable.
           2. update glibc to version 2.18. [1]
