+If RIFF/WAV data chunk length is shorter then expected for an audio

+CVE-2019-7635: Reject BMP images with pixel colors out the palette
+If a 1-, 4-, or 8-bit per pixel BMP image declares less used colors
+than the palette offers an SDL_Surface with a palette of the indicated
+number of used colors is created. If some of the image's pixel
+refer to a color number higher then the maximal used colors, a subsequent
+bliting operation on the surface will look up a color past a blit map
+(that is based on the palette) memory. I.e. passing such SDL_Surface
+to e.g. an SDL_DisplayFormat() function will result in a buffer overread in
+a blit function.
+
+This patch fixes it by validing each pixel's color to be less than the
+maximal color number in the palette. A validation failure raises an
+error from a SDL_LoadBMP_RW() function.

+Fixed bug 4500 - Heap-Buffer Overflow in Map1toN pertaining to SDL_pixels.c

+The reproducer has these data in BITMAPINFOHEADER:
+
+biSize = 40
+biBitCount = 8
+biClrUsed = 131075
+
+SDL_LoadBMP_RW() function passes biBitCount as a color depth to SDL_CreateRGBSurface(), thus 256-color pallete is allocated. But then biClrUsed colors are read from a file and stored into the palette. SDL_LoadBMP_RW should report an error if biClrUsed is greater than 2^biBitCount.

+CVE-2019-7637: Fix in integer overflow in SDL_CalculatePitch
+If a too large width is passed to SDL_SetVideoMode() the width travels
+to SDL_CalculatePitch() where the width (e.g. 65535) is multiplied by
+BytesPerPixel (e.g. 4) and the result is stored into Uint16 pitch
+variable. During this arithmetics an integer overflow can happen (e.g.
+the value is clamped as 65532). As a result SDL_Surface with a pitch
+smaller than width * BytesPerPixel is created, too small pixel buffer
+is allocated and when the SDL_Surface is processed in SDL_FillRect()
+a buffer overflow occurs.
+
+This can be reproduced with "./graywin -width 21312312313123213213213"
+command.
+
+This patch fixes is by using a very careful arithmetics in
+SDL_CalculatePitch(). If an overflow is detected, an error is reported
+back as a special 0 value. We assume that 0-width surfaces do not
+occur in the wild. Since SDL_CalculatePitch() is a private function,
+we can change the semantics.

+Subject: [PATCH] CVE-2019-7577: Fix a buffer overread in MS_ADPCM_nibble and
+ MS_ADPCM_decode
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If a chunk of RIFF/WAV file with MS ADPCM encoding contains an invalid
+predictor (a valid predictor's value is between 0 and 6 inclusive),
+a buffer overread can happen when the predictor is used as an index
+into an array of MS ADPCM coefficients.
+
+The overead happens when indexing MS_ADPCM_state.aCoeff[] array in
+MS_ADPCM_decode() and later when dereferencing a coef pointer in
+MS_ADPCM_nibble().
+
+This patch fixes it by checking the MS ADPCM predictor values fit
+into the valid range.
