CVE-2016-9395 (C, published 2017-03-23T18:59Z)
Description: value: The jas_seq2d_create function in jas_seq.c in JasPer before 1.900.25 allows remote attackers to cause a denial of service (assertion failure) via a crafted file.
Severity: MEDIUM (CVSS v3 base score: 5.5)
Weakness: CWE-20 \u2014 Improper Input Validation
The product receives input or data, but it does
        not validate or incorrectly validates that the input has the
        properties that are required to process the data safely and
        correctly.

Commit message: The generation of the configuration file jas_config.h has been completely
reworked in order to avoid pollution of the global namespace.

Some problematic types like uchar, ulong, and friends have been replaced
with names with a jas_ prefix.

An option max_samples has been added to the BMP and JPEG decoders to
restrict the maximum size of image that they can decode.  This change
was made as a (possibly temporary) fix to address security concerns.
A max_samples command-line option has also been added to imginfo.

Whether an image component (for jas_image_t) is stored in memory or on
disk is now based on the component size (rather than the image size).

Some debug log message were added.

Some new integer overflow checks were added.

Some new safe integer add/multiply functions were added.

More pre-C99 cruft was removed.  JasPer has numerous "hacks" to
handle pre-C99 compilers.  JasPer now assumes C99 support.  So, this
pre-C99 cruft is unnecessary and can be removed.

The regression jasper-doublefree-mem_close.jpg has been re-enabled.
Theoretically, it should work more predictably now.
