Subject: [slackware-security]:  glibc 2.1.3 vulnerabilities patched

Three locale-related vulnerabilities with glibc 2.1.3 were recently
reported on BugTraq.  These vulnerabilities could allow local users to
gain root access.

Users of Slackware 7.0, 7.1, and -current are strongly urged to upgrade to
the new glibc packages in the -current branch.



=========================================================================
glibc 2.1.3 AVAILABLE - (a1/glibcso.tgz, d1/glibc.tgz, des1/descrypt.tgz)
=========================================================================

The three locale-related vulnerabilities with glibc-2.1.3 have been
patched using the CVS glibc patches provided by Solar Designer.



PACKAGE INFORMATION:
--------------------
a1/glibcso.tgz:
   This package contains the runtime libraries for glibc 2.1.3.  All
   users of Slackware 7.0 through -current should upgrade this
   package.

d1/glibc.tgz:
   This is the full glibc 2.1.3 package, complete with headers and
   static libraries.  If you had previously installed this package,
   you need to upgrade it.

des1/descrypt.tgz:
   Contains a DES-enabled libcrypt.so library.  If you have this
   package, you need to upgrade it as well.  IMPORTANT:  Be sure to
   upgrade this package *AFTER* glibcso.tgz and glibc.tgz.


WHERE TO FIND THE NEW PACKAGES:

INSTALLATION INSTRUCTIONS:
--------------------------
The three packages above need to be upgraded in single user mode (runlevel
1).  Bring the system into runlevel 1:

   # telinit 1

Then upgrade the packages:

   # upgradepkg .tgz

Then bring the system back into multiuser mode:

   # telinit 3



Remember, it's also a good idea to backup configuration files before
upgrading packages.
