[slackware-security] gnutls (SSA:2008-315-01)

 

New gnutls packages are available for Slackware 12.0, 12.1, and -current to

fix a security issue.

 

NOTE: The package for 12.0 has a different shared library soname, and the

packages for 12.1 and -current have an API/ABI change. Only the Pidgin package

in Slackware links with GnuTLS, and upgraded Pidgin packages have also been

made available. However, if the updated GnuTLS package is installed any other

custom-compiled software that uses GnuTLS may need to be recompiled.

 

More details about this issue will become available in the Common

Vulnerabilities and Exposures (CVE) database:

 

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4989

 

 

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:

http://cve.mitre.org/cgi-bin/cvename.cgi?name=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 *)

Where to find the new packages:

+-----------------------------+

 

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

(http://osuosl.org) for donating additional FTP and rsync hosting

to the Slackware project! :-)

 

Also see the "Get Slack" section on http://slackware.com for

additional mirror sites near you.

 

Updated package for Slackware 12.0:

ftp://ftp.slackware.com/pub/slackware/slackware-12.0/patches/packages/gnutls-2.6.1-i486-1_slack12.0.tgz

 

Updated package for Slackware 12.1:

ftp://ftp.slackware.com/pub/slackware/slackware-12.1/patches/packages/gnutls-2.6.1-i486-1_slack12.1.tgz

 

Updated package for Slackware -current:

ftp://ftp.slackware.com/pub/slackware/slackware-current/slackware/n/gnutls-2.6.1-i486-1.tgz

 

 

MD5 signatures:

+-------------+

 

Slackware 12.0 package:

b2f8679618d7bca27161ee9e77e40be7 gnutls-2.6.1-i486-1_slack12.0.tgz

 

Slackware 12.1 package:

d71c4984aeb90571d57d55129913fa19 gnutls-2.6.1-i486-1_slack12.1.tgz

 

Slackware -current package:

a8bb0f8f70b96135a69e3eba04122e7a gnutls-2.6.1-i486-1.tgz

 

 

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.
