A security vulnerability has been discovered in libssh2 used with IBM Security Network Protection. Vulnerability Details CVEID: CVE-2016-0787 DESCRIPTION: libssh2 could provide weaker than expected security, caused by a type confusion error during the SSHv2 handshake resulting in the generation of a reduced amount of random bits for Diffie-Hellman. An attacker could exploit this vulnerability using the truncated Diffie-Hellman secret to launch further attacks on the system.

The Kerberos (krb5) version that is shipped with IBM Security Network Protection contains multiple security vulnerabilities. Vulnerability Details CVEID: CVE-2015-8629 DESCRIPTION: MIT Kerberos could allow a remote authenticated attacker to obtain sensitive information, caused by a null termination in the xdr_nullstring() function. By sending specially-crafted data, an attacker could exploit this vulnerability to obtain sensitive information from the memory. CVSS Base Score: 4.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110395 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2015-8631 DESCRIPTION: MIT Kerberos is vulnerable to a denial of service, caused by the leak of the client and server name by the rb5_unparse_name() function. By sending specially-crafted data, a remote authenticated attacker could exploit this vulnerability to consume all available memory resources. CVSS Base Score: 4.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/110393 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L) Affected Products and Versions IBM Security Network Protection 5.3.1 IBM Security Network Protection 5.3.2 Remediation/Fixes Product VRMF Remediation/First Fix IBM Security Network Protection Firmware version 5.3.1 Download Firmware 5.3.1.9 from IBM Security License Key and Download Center and upload and install via the Available Updates page of the Local Management Interface.
