Reflection for Secure IT	Reflection Software Version	Operating System *	Cryptographic Library	Cryptographic Library Version
Server and Client	7.1 **	Windows	rssccm.dll	2.0.40
Server and Client	7.1 **	Solaris, AIX, HP-UX, SuSE and Red Hat Enterprise Linux	libssccm.so.2.0.40, libssccm.sl.2.0.40	2.0.40 2.0.40
Server and Client	7.0 ***	Solaris, AIX, HP-UX, SuSE and Red Hat Enterprise Linux	libssccm.so.2.0.40, libssccm.sl.2.0.40	2.0.40

Security Alerts and Advisories for Reflection 7.x

The following security alerts and advisories may affect your Reflection installation, or the security of your operating system or network environment. We recommend that you review these alerts and advisories.

Note: This information is non-inclusive—it does not attempt to address all security issues that may affect your system.

Alert	Vulnerability Summary CVE-2009-2408
Date Posted	March 2010
Summary	An attacker could get a legitimate Certification Authority to issue a valid certificate containing a '\0' (NULL) character in the Common Name (CN) or SubjectAlternativeName fields. The presence of a NULL character could result in a client accepting a server certificate that appears to be legitimate, but is not.
Product Status	All versions of the PKI Services Manager properly handle a NULL character in a domain name in the CN field identifying the Subject of an X.509 certificate. This means that the service is not vulnerable to man-in-the-middle attackers to spoof arbitrary SSL or SSH servers using a crafted certificate issued by a legitimate Certification Authority (also known as the "Null Truncation in X.509 Common Name Vulnerability”).
Additional Information	For details of a similar issue, see the National Vulnerability Database web site at http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2009-2408.

Alert	Vulnerability Summary CVE-2009-2409
Date Posted	March 2010
Summary	Use of MD2 hashes in X.509 certificates might allow remote attackers to spoof intermediate CA certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. Note: The scope of this issue is currently limited because the amount of computation required is large.
Product Status	This issue is resolved in Reflection PKI Services Manager version 1.1 by not accepting MD2 signed intermediate CA certificates by default. A new setting is available if you need to enable use of intermediate certificates signed using this deprecated hash algorithm. From the console, enable "Allow MD2 signed certificates". Or, in the configuration file, set AllowMD2Certificates = yes.
Additional Information	For details of a similar issue, see the National Vulnerability Database web site at http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2009-2409.

Alert	US-CERT Technical Cyber Security Alert TA09-209A
Date Posted	28-July-2009
Summary	Vulnerabilities present in the Microsoft Active Template Library (ATL) can cause vulnerabilities in the resulting ActiveX controls and COM components, as described in Microsoft Security Bulletin MS09-035 and Microsoft Security Advisory 973882. Any ActiveX control or COM component that was created with a vulnerable version of the ATL may be vulnerable.
Product Status	While Reflection for Secure IT Windows Server and Reflection for Secure IT Windows Client do not contain ActiveX controls or COM components, these products do contain the vulnerable ATL. However, beginning in version 7.1 Service Pack 2, these products now contain the non-vulnerable ATL.
Additional Information	For details, see the US-CERT web site at http://www.us-cert.gov/cas/techalerts/TA09-209A.html.

Alert	Vulnerability Advisory CPNI-957037
Date Posted	October 2008
Summary	A design flaw in the SSH protocol use of block ciphers in cipher block chaining mode could allow an attacker to recover up to four bytes of plaintext. Although the severity of the attack is considered high, the likelihood of a successful attack is considered low and results in terminating the user’s SSH connection.
Product Status	For more information about how this vulnerability affects Attachmate products, see Technical Note 2398.
Additional Information	For details, see the Combined Security Incident Response Team - United Kingdom web site at http://www.cpni.gov.uk/Products/3716.aspx.

Alert	Vulnerability Summary CVE-2008-1657
Date Posted	July 2008
Summary	OpenSSH 4.4 and other versions before 4.9 allow remote authenticated users to bypass the sshd_config ForceCommand directive by modifying the .ssh/rc session file.
Product Status	The "ForceCommand" keyword is no longer supported as of Reflection for Secure IT UNIX Server version 7.0 SP1
Additional Information	For details, see the National Vulnerability Database web site at http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-1657.

Alert	Vulnerability Summary CVE-2008-1483
Date Posted	July 2008
Summary	OpenSSH 4.3p2, and probably other versions, allows local users to hijack forwarded X connections by causing ssh to set DISPLAY to :10, even when another process is listening on the associated port, as demonstrated by opening TCP port 6010 (IPv4) and sniffing a cookie sent by Emacs.
Product Status	This issue is resolved in Reflection for Secure IT UNIX Client version 7.0 SP1.
Additional Information	For details, see the National Vulnerability Database web site at http://nvd.nist.gov/nvd.cfm?cvename=CVE-2008-1483.

Alert	Vulnerability Summary CVE-2007-3108
Date Posted	July 2008
Summary	OpenSSL cryptography vulnerability that could allow an RSA key to be stolen.
Product Status	This issue is resolved in Reflection for Secure IT UNIX Client and Server version 7.0 SP1
Additional Information	For details, see the National Vulnerability Database web site at http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-3108.

Alert	Vulnerability Summary CVE-2006-2937
Date Posted	July 2008
Summary	Denial of Service attack using malformed ASN.1 packets.
Product Status	This issue is resolved in Reflection for Secure IT UNIX Client and Server version 7.0 SP1.
Additional Information	For details, see the National Vulnerability Database web site at http://nvd.nist.gov/nvd.cfm?cvename=CVE-2006-2937.

Alert	Vulnerability Summary CVE-2006-2940
Date Posted	July 2008
Summary	Denial of Service attack using parasitic public keys.
Product Status	This issue is resolved in Reflection for Secure IT UNIX Client and Server version 7.0 SP1.
Additional Information	For details, see the National Vulnerability Database web site at http://nvd.nist.gov/nvd.cfm?cvename=CVE-2006-2940.

Alert	Vulnerability Summary CVE-2007-4752
Date Posted	September 2007
Summary	ssh in OpenSSH before 4.7 does not properly handle when an untrusted cookie cannot be created and uses a trusted X11 cookie instead, which allows attackers to violate intended policy and gain privileges by causing an X client to be treated as trusted.
Product Status	Attachmate SSH clients (including Reflection for Secure IT and Reflection X) do not have this OpenSSH vulnerability. Note: Reflection for Secure IT UNIX Clients versions 6.x and 7.0 support trusted X11 forwarding, but do not have the vulnerability.
Additional Information	For details, see the National Vulnerability Database web site at http://nvd.nist.gov/nvd.cfm?cvename=CVE-2007-4752.
