Fedora 7 : libpng10-1.0.29-1.fc7 (2007-2521)

This script is Copyright (C) 2007-2016 Tenable Network Security, Inc.


Synopsis :

The remote Fedora host is missing a security update.

Description :

Certain chunk handlers in libpng10 before 1.0.29 allow remote
attackers to cause a denial of service (crash) via crafted (1) pCAL
(png_handle_pCAL), (2) sCAL (png_handle_sCAL), (3) tEXt
(png_push_read_tEXt), (4) iTXt (png_handle_iTXt), and (5) ztXT
(png_handle_ztXt) chunking in PNG images, which trigger out-of-bounds
read operations.
