"... fixes a double-gamma-correction bug on colormapped images with partially transparent palette entries, as well as a number of problems (believed to be benign) that were found by the Coverity static-analysis tool."
"Most versions of libpng up through 1.2.24 have a number of minor coding errors that could lead to crashes in exceptional cases. For example, if memory allocation fails while processing certain ancillary chunks, libpng could crash while attempting to write to the NULL pointer; or if the application author failed to set up the info_ptr as required, some parts of libpng fail to check for NULL and could crash trying to read the pointer (though it's probable that the error would have caused libpng to terminate upstream of these parts). The bugs are fixed in version 1.2.25, released 18 February 2008."
