| Description: | Summary:
The remote host is missing an update for the 'libpng10'
package(s) announced via the referenced advisory.
Vulnerability Insight:
The libpng packages contain a library of functions for creating and
manipulating PNG (Portable Network Graphics) image format files.
A flaw was discovered in libpng that could result in libpng trying to
free() random memory if certain, unlikely error conditions occurred. If a
carefully-crafted PNG file was loaded by an application linked against
libpng, it could cause the application to crash or, potentially, execute
arbitrary code with the privileges of the user running the application.
(CVE-2009-0040)
A flaw was discovered in the way libpng handled PNG images containing
'unknown' chunks. If an application linked against libpng attempted to
process a malformed, unknown chunk in a malicious PNG image, it could cause
the application to crash. (CVE-2008-1382)
Users of libpng and libpng10 should upgrade to these updated packages,
which contain backported patches to correct these issues. All running
applications using libpng or libpng10 must be restarted for the update to
take effect.
Affected Software/OS:
libpng10 on CentOS 4
Solution:
Please install the updated packages.
