[slackware-security]  libpng (SSA:2008-119-01)

New libpng packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1,
10.2, 11.0, 12.0, and -current to fix a security issue.

More details about this issue may be found in the Common
Vulnerabilities and Exposures (CVE) database:

  http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1382

Additional information can be found in the libpng source, or in this
file on the libpng FTP site:

  ftp://ftp.simplesystems.org/pub/libpng/png/src/libpng-1.2.27-README.txt


Here are the details from the Slackware 12.0 ChangeLog:
+--------------------------+
patches/packages/libpng-1.2.27-i486-1_slack12.0.tgz:
  Upgraded to libpng-1.2.27.
  This fixes various bugs, the most important of which have to do with the
  handling of unknown chunks containing zero-length data.  Processing a PNG
  image that contains these could cause the application using libpng to crash
  (possibly resulting in a denial of service), could potentially expose the
  contents of uninitialized memory, or could cause the execution of arbitrary
  code as the user running libpng (though it would probably be quite difficult
  to cause the execution of attacker-chosen code).  We recommend upgrading the
  package as soon as possible.
  For more information, see:
    http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1382

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.
