Description Andrej Nemec 2016-04-14 13:20:23 UTC 
Heap-based buffer overflow in the bmp_read_rows function in pngxrbmp.c
in OptiPNG before 0.7.6 allows remote attackers to cause a denial of
service (out-of-bounds read or write access and crash) or possibly
execute arbitrary code via a crafted image file.
