SecurID appliance 3.0.4
|OS||Linux (x64) - SLES 11.x|
|Link to Advisories||https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2015-1793|
|Alert Impact||Not Applicable|
|Technical Details||False positive|
|Technical Details Explanation||Response: The flaw does not exist|
AM 7.1.4 - Does not use OpenSSL
Response: The flaw does not exist
AM 3.0.4 Appliance and AM 8.1.1 - Do not use a vulnerable version of OpenSSL
Note: At the current time, AM 8.1.1 uses OpenSSL versions: 0.9.8j-fips and 1.0.1h
and AM 3.0.4 Appliance uses OpenSSL 0.9.7f (for SSH not AM).
Note: AM 7.1.4 and AM 3.0.4 Appliance have now reached the end of primary support and the end of secondary support (phase one) as well.
|Notes||Alternative chains certificate forgery (CVE-2015-1793)|
During certificate verification, OpenSSL (starting from version 1.0.1n and
1.0.2b) will attempt to find an alternative certificate chain if the first
attempt to build such a chain fails. An error in the implementation of this
logic can mean that an attacker could cause certain checks on untrusted
certificates to be bypassed, such as the CA flag, enabling them to use a valid
leaf certificate to act as a CA and "issue" an invalid certificate.
This issue will impact any application that verifies certificates including
SSL/TLS/DTLS clients and SSL/TLS/DTLS servers using client authentication.
This issue affects OpenSSL versions 1.0.2c, 1.0.2b, 1.0.1n and 1.0.1o.
OpenSSL 1.0.2b/1.0.2c users should upgrade to 1.0.2d
OpenSSL 1.0.1n/1.0.1o users should upgrade to 1.0.1p
This issue was reported to OpenSSL on 24th June 2015 by Adam Langley/David
Benjamin (Google/BoringSSL). The fix was developed by the BoringSSL project.
