Description

Updated openssl packages that fix several security issues are now available for CentOS Linux 5. The CentOS Security Response Team has rated this update as having important 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. 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 cause an application using the OpenSSL library to crash or, possibly, execute arbitrary code. (CVE-2009-3245) A flaw was found in the way the TLS/SSL (Transport Layer Security/Secure Sockets Layer) protocols handled session renegotiation. A man-in-the-middle attacker could use this flaw to prefix arbitrary plain text to a client's session (for example, an HTTPS connection to a website). This could force the server to process an attacker's request as if authenticated using the victim's credentials. This update addresses this flaw by implementing the TLS Renegotiation Indication Extension, as defined in RFC 5746. (CVE-2009-3555) Refer to the following Knowledgebase article for additional details about the CVE-2009-3555 flaw: http://kbase.redhat.com/faq/docs/DOC-20491 A missing return value check flaw was discovered in OpenSSL, that could possibly cause OpenSSL to call a Kerberos library function with invalid arguments, resulting in a NULL pointer dereference crash in the MIT Kerberos library. In certain configurations, a remote attacker could use this flaw to crash a TLS/SSL server using OpenSSL by requesting Kerberos cipher suites during the TLS handshake. (CVE-2010-0433) 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.

Solution

  • CentOS Linux >= 5 and < 6 (iSeries)

    Upgrade openssl

    Update openssl to the latest version available from CentOS, using tools like yum or up2date.

    Because CentOS RPMs are built off of RedHat SRPMs, there is a delay between when a vulnerability is published and fixed in the RedHat SRPMs and the time that CentOS in turn rebuilds and redistributes the updated RPMs. As such, there may be cases where the updated RPM(s) listed here might not exist in the CentOS RPM repositories yet.

  • CentOS Linux >= 5 and < 6 (iSeries)

    Upgrade openssl-devel

    Update openssl-devel to the latest version available from CentOS, using tools like yum or up2date.
