Summary
It was discovered that there were multiple heap-based buffer overflows in ming, a library to generate SWF (Flash) files. The updated packages prevent a crash in the 'listswf' utility due to a heap-based buffer overflow in the parseSWF_RGBA function and several other functions in parser.c. AddressSanitizer flagged them as invalid writes 'of size 1' but the heap could be written to multiple times. The overflows are caused by a pointer behind the bounds of a statically allocated array of structs of type SWF_GRADIENTRECORD.
