JSA10544 - 2012-11 Security Bulletin: Steel-Belted Radius: Multiple OpenSSL Vulnerabilities

OpenSSL software distributed with Steel-Belted Radius is vulnerable to CVE-2011-4619, and CVE-2011-4576. These may allow decrypting encrypted information or cause a denial of service condition for the Steel-Belted Radius server.

CVE-2011-4576 The SSL 3.0 implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly initialize data structures for block cipher padding, which might allow remote attackers to obtain sensitive information by decrypting the padding data sent by an SSL peer.
CVSS v2 Base Score:5.0 (AV:N/AC:L/Au:N/C:P/I:N/A:N)

CVE-2011-4619 The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service condition.
CVSS v2 Base Score:5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P)

These vulnerabilities are fixed in:
Steel-Belted Radius Carrier (SBR Carrier) 7.4.1 or later
SBR EE Software 6.1.7 or later
SBR GE Software 6.1.7 or later
 

 

There are no viable workarounds that can mitigate these vulnerabilities for Steel-Belted Radius products.
Use access lists or firewall filters to limit access to the Steel-Belted Radius server only from trusted hosts.
