-Subject: [PATCH] convertbmp: fix issues with zero bitmasks
-
-In the case where a BMP file declares compression 3 (BI_BITFIELDS)
-with header size <= 56, all bitmask values keep their initialization
-value 0. This may lead to various undefined behavior later e.g. when
-doing 1 << (l_comp->prec - 1).
-
-This issue does not affect files with bit count 16 because of a check
-added in 16240e2 which sets default values to the color masks if they
-are all 0.
-
-This commit adds similar checks for the 32 bit case.
-
-Also, if a BMP file declares compression 3 with header size >= 56 and
-intentional 0 bitmasks, the same issue will be triggered in both the
-16 and 32 bit count case.
-
-This commit adds checks to bmp_read_info_header() rejecting BMP files
-with "intentional" 0 bitmasks. These checks might be removed in the
-future when proper handling of zero bitmasks will be available in
-openjpeg2.
-
-fixes #1057 (CVE-2018-5785)

-Subject: [PATCH] opj_mj2_extract: Check provided output prefix for length
-
-This uses snprintf() with correct buffer length instead of sprintf(). This
-prevents a buffer overflow when providing a long output prefix. Furthermore
-the program exits with an error when the provided output prefix is too long.
-
-Fixes #1088.
