| Matt Sarett | 9ea7569 | 2016-01-08 13:00:42 -0500 | [diff] [blame] | 25 | Changes since the last public release (1.6.19): |
| 26 | Avoid potential pointer overflow/underflow in png_handle_sPLT() and |
| 27 | png_handle_pCAL() (Bug report by John Regehr). |
| 28 | Fixed incorrect implementation of png_set_PLTE() that uses png_ptr |
| 29 | not info_ptr, that left png_set_PLTE() open to the CVE-2015-8126 |
| 30 | vulnerability. |
| 31 | Backported tests from libpng-1.7.0beta69. |
| 32 | Fixed an error in handling of bad zlib CMINFO field in pngfix, found by |
| 33 | American Fuzzy Lop, reported by Brian Carpenter. inflate() doesn't |
| 34 | immediately fault a bad CMINFO field; instead a 'too far back' error |
| 35 | happens later (at least some times). pngfix failed to limit CMINFO to |
| 36 | the allowed values but then assumed that window_bits was in range, |
| 37 | triggering an assert. The bug is mostly harmless; the PNG file cannot |
| 38 | be fixed. |
| 39 | In libpng 1.6 zlib initialization was changed to use the window size |
| 40 | in the zlib stream, not a fixed value. This causes some invalid images, |
| 41 | where CINFO is too large, to display 'correctly' if the rest of the |
| 42 | data is valid. This provides a workaround for zlib versions where the |
| 43 | error arises (ones that support the API change to use the window size |
| 44 | in the stream). |
