Scientific Linux Security Update : nss on SL4.x, SL5.x, SL6.x i386/x86_64

high Nessus Plugin ID 61175

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Network Security Services (NSS) is a set of libraries designed to support the development of security-enabled client and server applications.

It was found that the Malaysia-based Digicert Sdn. Bhd. subordinate Certificate Authority (CA) issued HTTPS certificates with weak keys.
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. Note: Digicert Sdn. Bhd. is not the same company as found at digicert.com.

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.

This update also fixes the following bug on Scientific Linux 5 :

- When using mod_nss with the Apache HTTP Server, a bug in NSS on Scientific Linux 5 resulted in file descriptors leaking each time the Apache HTTP Server was restarted with the 'service httpd reload' command. This could have prevented the Apache HTTP Server from functioning properly if all available file descriptors were consumed.

For Scientific Linux 6, these updated packages upgrade NSS to version 3.12.10. As well, they upgrade NSPR (Netscape Portable Runtime) to version 4.8.8 and nss-util to version 3.12.10 on Scientific Linux 6, as required by the NSS update.

All NSS users should upgrade to these updated packages, which correct this issue. After installing the update, applications using NSS must be restarted for the changes to take effect. In addition, on Scientific Linux 6, applications using NSPR and nss-util must also be restarted.

Solution

Update the affected packages.
