NONE Summary
OpenSSL before 0.9.8j, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled, does not prevent modification of the ciphersuite in the session cache, which allows remote attackers to force the use of a disabled cipher via vectors involving sniffing network traffic to discover a session identifier, a different vulnerability than CVE-2010-4180.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Signature Spoofing by Key Recreation An attacker obtains an authoritative or reputable signer's private signature key by exploiting a cryptographic weakness in the signature algorithm or pseudorandom number generation and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.
Nessus
NASL family General NASL id OPENSSL_RESUME_DISABLED_CIPHER.NASL description The version of OpenSSL on the remote host has been shown to allow the use of disabled ciphers when resuming a session. This means that an attacker that sees (e.g. by sniffing) the start of an SSL connection can manipulate the OpenSSL session cache to cause subsequent resumptions of that session to use a disabled cipher chosen by the attacker. last seen 2020-06-01 modified 2020-06-02 plugin id 51893 published 2011-02-07 reporter This script is Copyright (C) 2011-2018 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/51893 title OpenSSL SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG Ciphersuite Disabled Cipher Issue NASL family VMware ESX Local Security Checks NASL id VMWARE_VMSA-2011-0013.NASL description a.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. A ciphersuite downgrade flaw was found in the OpenSSL SSL/TLS server code. A remote attacker could possibly use this flaw to change the ciphersuite associated with a cached session stored on the server, if the server enabled the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option, possibly forcing the client to use a weaker ciphersuite after resuming the session. (CVE-2010-4180, CVE-2008-7270) Note: With this update, setting the SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG option has no effect and this bug workaround can no longer be enabled. It was discovered that OpenSSL did not always check the return value of the bn_wexpand() function. An attacker able to trigger a memory allocation failure in that function could possibly crash an application using the OpenSSL library and its UBSEC hardware engine support. (CVE-2009-3245) All OpenSSL users should upgrade to these updated packages, which contain backported patches to resolve these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted. last seen 2020-06-01 modified 2020-06-02 plugin id 68163 published 2013-07-12 reporter This script is Copyright (C) 2013-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/68163 title Oracle Linux 4 : openssl (ELSA-2010-0977) NASL family CentOS Local Security Checks NASL id CENTOS_RHSA-2010-0978.NASL description Updated openssl packages that fix two security issues are now available for Red Hat Enterprise Linux 5.
