Description Victor Pereira 2015-01-13 13:52:31 UTC

A heap-based overflow was found in the png_combine_row() function of the libpng library, when very large interlaced images were used. This flaw was fixed in libpng-1.5.21 and 1.6.16.

Upstream patch:

http://sourceforge.net/p/libpng/code/ci/dc294204b641373bc6eb603075a8b98f51a75dd8/

Hmm, this is exactly the same commit that you provide in bug 912076 comment 0. What I am missing?
