[SECURITY] libpng vulnerabilities

[Yaakov (Cygwin/X)]

Chuck,

All versions of libpng have recently announced security vulnerabilities:

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-2690
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-2691
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-2692

Remedy:
Update libpng10 to 1.0.55 (or just remove it, as nothing in the distro
depends on it any more), libpng12 to 1.2.45, and libpng14 to 1.4.8.

Thanks,


Yaakov
