Fedora 28: libpng10 Security Update

July 29, 2018

Fix for CVE-2018-13785: the libpng10 library was vulnerable to an integer overflow and resultant divide-by-zero in the pngrutil.c:png_check_chunk_length() function

Summary

The libpng10 package contains an old version of libpng, a library of functions

for creating and manipulating PNG (Portable Network Graphics) image format

files.

This package is needed if you want to run binaries that were linked dynamically

with libpng 1.0.x.

Fix for CVE-2018-13785: the libpng10 library was vulnerable to an integer

overflow and resultant divide-by-zero in the

pngrutil.c:png_check_chunk_length() function. An attacker could exploit this to

cause a denial of service via a crafted PNG file.
