Summary: Updated nss and nspr packages that fix one security issue are now available for Red Hat Enterprise Linux 4, 5, and 6. The Red Hat Security Response Team has rated this update as having important security impact. 2. Relevant releases/architectures: RHEL Desktop Workstation (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64 Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64 Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. Netscape Portable Runtime (NSPR) providesplatform independence for non-GUI operating system facilities. It was found that a Certificate Authority (CA) issued fraudulent HTTPS certificates. This update renders any HTTPS certificates signed by that CA as untrusted. This covers all uses of the certificates, including SSL, S/MIME, and code signing. (BZ#734316) Note: This fix only applies to applications using the NSS Builtin Object Token. It does not render the certificates untrusted for applications that use the NSS library, but do not use the NSS Builtin Object Token. These updated packages upgrade NSS to version 3.12.10 on Red Hat Enterprise Linux 4 and 5. As well, they upgrade NSPR to version 4.8.8 on Red Hat Enterprise Linux 4 and 5, as required by the NSS update. The packages for Red Hat Enterprise Linux 6 include a backported patch. All NSS and NSPR users should upgrade to these updated packages, which correct this issue. After installing the update, applications using NSS and NSPR must be restarted for the changes to take effect. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/kb/docs/DOC-11259 5. Bugs fixed (http://bugzilla.redhat.com/): 734316 - Fraudulent certificates signed by DigiNotar CA certificate (MFSA 2011-34) 6.

Updated nspr and nss packages that fix security issues and bugs are now available for Red Hat Enterprise Linux 4.7 Extended Update Support. This update has been rated as having critical security impact by the Red Hat Security Response Team.. ==================================================================== Red Hat Security Advisory Synopsis: Critical: nspr and nss security and bug fix update Advisory ID: RHSA-2009:1190-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2009:1190.html Issue date: 2009-07-31 CVE Names: CVE-2009-2404 CVE-2009-2408 CVE-2009-2409 ==================================================================== 1. Summary: Updated nspr and nss packages that fix security issues and bugs are now available for Red Hat Enterprise Linux 4.7 Extended Update Support. This update has been rated as having critical security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4.7.z - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux ES version 4.7.z - i386, ia64, x86_64 3. Description: Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities. These facilities include threads, thread synchronization, normal file and network I/O, interval timing, calendar time, basic memory management (malloc and free), and shared library linking. Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. Applications built with NSS can support SSLv2, SSLv3, TLS, and other security standards. These updated packages upgrade NSS from the previous version, 3.12.2, to a prerelease of version 3.12.4. The version of NSPR has also been upgraded from 4.7.3 to 4.7.4. Moxie Marlinspike reported a heap overflow flaw in a regular expression parser in the NSS library used by browsers such as MozillaFirefox to match common names in certificates. A malicious website could present a carefully-crafted certificate in such a way as to trigger the heap overflow, leading to a crash or, possibly, arbitrary code execution with the permissions of the user running the browser. (CVE-2009-2404) Note: in order to exploit this issue without further user interaction in Firefox, the carefully-crafted certificate would need to be signed by a Certificate Authority trusted by Firefox, otherwise Firefox presents the victim with a warning that the certificate is untrusted. Only if the user then accepts the certificate will the overflow take place. Dan Kaminsky discovered flaws in the way browsers such as Firefox handle NULL characters in a certificate. If an attacker is able to get a carefully-crafted certificate signed by a Certificate Authority trusted by Firefox, the attacker could use the certificate during a man-in-the-middle attack and potentially confuse Firefox into accepting it by mistake. (CVE-2009-2408) Dan Kaminsky found that browsers still accept certificates with MD2 hash signatures, even though MD2 is no longer considered a cryptographically strong algorithm. This could make it easier for an attacker to create a malicious certificate that would be treated as trusted by a browser. NSS now disables the use of MD2 and MD4 algorithms inside signatures by default. (CVE-2009-2409) These version upgrades also provide fixes for the following bugs: * SSL client authentication failed against an Apache server when it was using the mod_nss module and configured for NSSOCSP. On the client side, the user agent received an error message that referenced "Error Code: - -12271" and stated that establishing an encrypted connection had failed because the certificate had been rejected by the host. On the server side, the nss_error_log under /var/log/httpd/ contained the following message: [error] Re-negotiation handshake failed: Not accepted by client!? Also, /var/log/httpd/error_log contained this error: SSL Library Error:-8071 The OCSP server experienced an internal error With these updated packages, the dependency problem which caused this failure has been resolved so that SSL client authentication with an Apache web server using mod_nss which is configured for NSSOCSP succeeds as expected. Note that if the presented client certificate is expired, then access is denied, the user agent is presented with an error message about the invalid certificate, and the OCSP queries are seen in the OCSP responder. Also, similar OCSP status verification happens for SSL server certificates used in Apache upon instance start or restart. (BZ#508026) * NSS uses a software integrity test to detect code corruption. RPM transactions and system link optimization daemons (such as prelink) can change the contents of libraries, causing the software integrity test to fail. In combination with the updated prelink package (RHBA-2009:1041), these updated packages can now prevent software integrity test failures. (BZ#495938) All users of nspr and nss are advised to upgrade to these updated packages, which resolve these issues. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at 5. Bugs fixed (http://bugzilla.redhat.com/): 495938 - seamonkey/nss FIPS mode failure, update prelink and nss 508026 - rhcs80beta TPS and mod_nss with NSSOCSP has ssl errors and unable to use agent service 510197 - CVE-2009-2409 deprecate MD2 in SSL cert validation (Kaminsky) 510251 - CVE-2009-2408 firefox/nss: doesn't handle NULL in Common Name properly 512912 - CVE-2009-2404 nss regexp heap overflow 6.
