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:


All new packages can be found in the -current branch:

ftp://ftp.slackware.com/pub/slackware/slackware-current/slakware/a1/glibcso.tgz
ftp://ftp.slackware.com/pub/slackware/slackware-current/slakware/d1/glibc.tgz
ftp://ftp.slackware.com/pub/slackware/slackware-current/slakware/des1/descrypt.tgz

MD5 SIGNATURES AND CHECKSUMS:


Here are the md5sums and checksums for the 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.
