It fixes several security issues: 1. A last instance of CVE-2016-2317 (heap buffer overflow) in the MVG rendering code (also impacts SVG). This problem was originally reported by Gustavo Grieco. 2. A possible heap overflow of the EscapeParenthesis() function. While I was not able to reproduce it for myself, the implementation is replaced with a different algorithm. This problem was reported by Gustavo Grieco. 3. The Utah RLE reader did not validate that header information was reasonable given the file size and so it could cause huge memory allocations and/or consume huge amounts of CPU. This problem was reported by Agostino Sarubbo. 4. The TIFF reader had a bug pertaining to use of TIFFGetField() when a 'count' value is returned. The bug caused a heap read overflow (due to using strlcpy() to copy a possibly unterminated string) which could allow an untrusted file to crash the software. The project appreciates the time and effort that various security researchers have expended to identify security issues with the software so that they may be fixed.
