Name : libpng10
Product : Fedora 27
Version : 1.0.69
Release : 5.fc27
URL : http://www.libpng.org/pub/png/libpng.html
Summary : Old version of libpng, needed to run old binaries
Description :
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.
--------------------------------------------------------------------------------
Update Information:
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.
