libexif (SSA:2007-164-01)
Posted on: 06/14/2007 09:15 AM

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:

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.
