Slackware 12.1: 2008-315-01 Critical: GnuTLS API and Security Update

Dist Slackware Esm H88
Recent updates to gnutls packages for Slackware address critical security vulnerabilities; an API modification necessitates that certain applications be recompiled.
New gnutls packages are available for Slackware 12.0, 12.1, and -current to fix a security issue

Summary

Here are the details from the Slackware 12.1 ChangeLog: patches/packages/gnutls-2.6.1-i486-1_slack12.1.tgz: Upgraded to gnutls-2.6.1. From the gnutls-2.6.1 NEWS file: ** libgnutls: Fix X.509 certificate chain validation error. [GNUTLS-SA-2008-3] The flaw makes it possible for man in the middle attackers (i.e., active attackers) to assume any name and trick GNU TLS clients into trusting that name. Thanks for report and analysis from Martin von Gagern . [CVE-2008-4989] For more information, see: https://www.cve.org/CVERecord?id=CVE-2008-4989 IMPORTANT NOTE: This update modifies the API and ABI for the gnutls_pk_params_st function. Any software that uses the function will need to be recompiled. (* Security fix *)

HINT: Getting slow download speeds from ftp.slackware.com? Give slackware.osuosl.org a try. This is another primary FTP site for Slackware that can be considerably faster than downloading directly from ftp.slackware.com.
Thanks to the friendly folks at the OSU Open Source Lab (https://osuosl.org/) for donating additional FTP and rsync hosting to the Slackware project! :-)

Installation Instructions

Installation instructions: Upgrade the package as root: # upgradepkg gnutls-2.6.1-i486-1_slack12.1.tgz Also install the new Pidgin package if you use it. Slackware 12.0 will require a recompile of any locally compiled GnuTLS linked packages. Recompiling locally compiled GnuTLS linked software is also recommended with Slackware 12.1 and -current, although it is probable that a lot of software would work without a recompile since only a single function (gnutls_pk_params_st) was changed.
