Security Bulletin: Multiple vulnerabilities in IBM Security Network Protection (CVE-2014-3567, CVE-2014-4877, CVE-2014-3513, CVE-2014-3566, CVE-2014-3567, CVE-2014-3568)

Summary

An OpenSSL and a Wget vulnerability have been discovered in IBM Security Network Protection.

Vulnerability Details

CVEID: CVE-2014-4877

DESCRIPTION: GNU Wget could allow a remote attacker to launch a symlink attack. Temporary files are created insecurely. A remote attacker could exploit this vulnerability by creating a symbolic link from a temporary file to various files on the system, which could allow the attacker to overwrite arbitrary files and possibly execute arbitrary code on the system.

CVSS Base Score: 6.8

CVEID: CVE-2014-3567

DESCRIPTION: OpenSSL is vulnerable to a denial of service caused by a memory leak when handling failed session ticket integrity checks. By sending an overly large number of invalid session tickets, an attacker could exploit this vulnerability to exhaust all available memory of an SSL/TLS or DTLS server.

CVSS Base Score: 5.0

CVE-ID:CVE-2014-3513

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory leak in the DTLS Secure Real-time Transport Protocol (SRTP) extension parsing code. By sending multiple specially-crafted handshake messages, an attacker could exploit this vulnerability to exhaust all available memory of an SSL/TLS or DTLS server.

CVE-ID: CVE-2014-3566

DESCRIPTION: Multiple products could allow a remote attacker to obtain sensitive information, caused by a design error when using the SSLv3 protocol. A remote user with the ability to conduct a man-in-the-middle attack could exploit this vulnerability via the POODLE (Padding Oracle On Downgraded Legacy Encryption) attack to decrypt SSL sessions and calculate the plaintext of secure connections.

CVE-ID: CVE-2014-3568

DESCRIPTION: OpenSSL could allow a remote attacker bypass security restrictions. When configured with “no-ssl3” as a build option, servers could accept and complete a SSL 3.0 handshake. An attacker could exploit this vulnerability to perform unauthorized actions.
