check ${S}/libraries/png.
megapov is at least affected by CVE-2008-5709 (c.f. bug 255231). For susceptibility to CVE-2008-5907, only 2 out of 3 needed requirements are met. I didn't check for other issues, but the one hit is enough for me to take action: Graphics, can you rip out libpng? If not, as upstream development seems to have stopped and no package RDPENEDS on it, we'd have to consider megapov as a candidate for removal.
No response from maintainers. Treecleaners, please proceed to last rites.

libpng was rated B2 in bug #255231
