[slackware-security]  libexif (SSA:2007-164-01)

New libexif packages are available for Slackware 10.2, 11.0, and -current to
fix a crash and potential 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-2007-4168

Here are the details from the Slackware 11.0 ChangeLog:
+--------------------------+
l/libexif-0.6.16-i486-1_slack11.0.tgz:  Upgraded to libexif-0.6.16.
  An integer overflow in libexif can crash applications that use the library
  on malformed images.  The upstream advisory indicates that this flaw could
  also be used to execute arbitrary code in the context of the user, but no
  exploit is known (by us) to exist among iDefense's researchers or in the
  wild.  But, as a crash bug and heap overflow one must suppose that the
  possibility exists.

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
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.
