https://github.com/clearlinux-pkgs/SDL2_image/commit/d08cf4a78b0bfacc31af213089734250870fdc8d

修复方法：
在components/SDL2/src/image/SDL_bmp.c文件中的SDL_LoadBMP_RW函数中，第353行后, 插入如下代码（插入后该代码段为354-358行）:
if (biWidth <= 0 || biHeight == 0) {
SDL_SetError("BMP file with bad dimensions (%dx%d)", biWidth, biHeight);
was_error = SDL_TRUE;
goto done;
}

考虑到其可能存在的潜在风险，我愿意配合您以负责任的方式及时核实、解决和报告发现的漏洞。 如果您需要任何进一步的信息或帮助，请随时与我联系。如果需要，我也可以提交PR帮助您修复。 谢谢您，期待尽快收到您的回复！

Read components/SDL2/src/image/IMG_bmp.c and locate SDL_LoadBMP_RW; reconcile the body’s alternate SDL_bmp.c path with the referenced CVE-2019-13616 fix. Compare the current behavior with the linked commit and confirm the reported out-of-bounds-read condition is addressed, then validate with the project’s existing checks.
