Vulnerability Assessment Details

SUSE-SA:2004:023: libpng

Vulnerability Assessment Summary
Check for the version of the libpng package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory
SUSE-SA:2004:023 (libpng).


Several different security vulnerabilities were found in the PNG
library which is used by applications to support the PNG image format.

A remote attacker would be able to execute arbitrary code by triggering a
buffer overflow due to the incorrect handling of the length of
transparency chunk data and in other pathes of image processing.

A special PNG image can be used to cause an application crashing due
to NULL pointer dereference in the function png_handle_iCPP() (and
other locations).

Integer overflows were found in png_handle_sPLT(), png_read_png()
functions and other locations. These bugs may at least crash an
application.
