OpenPKG Security Advisory - As confirmed by the vendor, a Denial of Service (DoS) vulnerability exists in the PNG image format library libpng. The bug is a NULL-pointer-dereference vulnerability involving palette images with a malformed "tRNS" PNG chunk, i.e., one with a bad CRC value. This bug can, at a minimum, cause crashes in applications simply by displaying a malformed image.
