- update to 2.1.5.1:
* Fixed a regression introduced by 2.0 beta1[15] that caused a buffer
overrun in the progressive Huffman encoder when attempting to transform
a specially-crafted malformed 12-bit-per-component JPEG image into a
progressive 12-bit-per-component JPEG image using a 12-bit-per-component
build of libjpeg-turbo.
* Fixed an issue whereby, when using a 12-bit-per-component build of
libjpeg-turbo (-DWITH_12BIT=1), passing samples with values greater than 4095
or less than 0 to jpeg_write_scanlines() caused a buffer overrun or
underrun in the RGB-to-YCbCr color converter.
* Fixed a floating point exception that occurred when attempting to use
the jpegtran -drop and -trim options to losslessly transform a
specially-crafted malformed JPEG image.
* Fixed an issue in tjBufSizeYUV2() whereby it returned a bogus result,
rather than throwing an error, if the align parameter was not a power of 2.
* Fixed a similar issue in tjCompressFromYUV() whereby it generated a corrupt
JPEG image in certain cases, rather than throwing an error,
if the align parameter was not a power of 2.
* Fixed an issue whereby tjDecompressToYUV2(), which is a wrapper for
tjDecompressToYUVPlanes(), used the desired YUV image dimensions
rather than the actual scaled image dimensions when computing the plane
pointers and strides to pass to tjDecompressToYUVPlanes().
This caused a buffer overrun and subsequent segfault if the desired
image dimensions exceeded the scaled image dimensions.
* Fixed an issue whereby, when decompressing a 12-bit-per-component JPEG
image (-DWITH_12BIT=1) using an alpha-enabled output color space such as
JCS_EXT_RGBA, the alpha channel was set to 255 rather than 4095.
* Fixed an issue whereby the Java version of TJBench did not accept a range
of quality values.
* Fixed an issue whereby, when -progressive was passed to TJBench,
