The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0977 advisory.

  - openssl: NETSCAPE_REUSE_CIPHER_CHANGE_BUG downgrade-to-disabled ciphersuite attack (CVE-2008-7270)

  - openssl: missing bn_wexpand return value checks (CVE-2009-3245)

  - openssl: NETSCAPE_REUSE_CIPHER_CHANGE_BUG ciphersuite downgrade attack (CVE-2010-4180)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote HP ProCurve switch is missing a software update that corrects an issue where an attacker could remotely cause an unauthorized information disclosure.

Updated openssl packages that fix three security issues are now available for Red Hat Enterprise Linux 4.

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.

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.

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.

Updated openssl packages that fix two security issues are now available for Red Hat Enterprise Linux 5.

f. Integer overflow in VMware third-party component sfcb

   This release resolves an integer overflow issue present in the    third-party library SFCB when the httpMaxContentLength has been    changed from its default value to 0 in in /etc/sfcb/sfcb.cfg.
   The integer overflow could allow remote attackers to cause a    denial of service (heap memory corruption) or possibly execute    arbitrary code via a large integer in the Content-Length HTTP    header.
     The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the name CVE-2010-2054 to this issue.

The remote VMware ESX / ESXi host is missing a security-related patch.
It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities, in several third-party components and libraries :

  - Java Runtime Environment (JRE)
  - libuser
  - Netscape Portable Runtime (NSPR) 
  - Network Security Services (NSS)
  - OpenSSL

It was discovered that an old bug workaround in the SSL/TLS server code allowed an attacker to modify the stored session cache ciphersuite. This could possibly allow an attacker to downgrade the ciphersuite to a weaker one on subsequent connections. (CVE-2010-4180)

It was discovered that an old bug workaround in the SSL/TLS server code allowed an attacker to modify the stored session cache ciphersuite. An attacker could possibly take advantage of this to force the use of a disabled cipher. This vulnerability only affects the versions of OpenSSL in Ubuntu 6.06 LTS, Ubuntu 8.04 LTS, and Ubuntu 9.10. (CVE-2008-7270).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
