8 | CVE-2019-7572: Fix a buffer overwrite in IMA_ADPCM_decode | ||
9 | If data chunk was longer than expected based on a WAV format | ||
10 | definition, IMA_ADPCM_decode() tried to write past the output | ||
11 | buffer. This patch fixes it. | ||
12 | |||

28 | CVE-2019-7572: Fix a buffer overread in IMA_ADPCM_nibble | ||
29 | If an IMA ADPCM block contained an initial index out of step table | ||
30 | range (loaded in IMA_ADPCM_decode()), IMA_ADPCM_nibble() blindly used | ||
31 | this bogus value and that lead to a buffer overread. | ||
32 | |||
33 | This patch fixes it by moving clamping the index value at the | ||
34 | beginning of IMA_ADPCM_nibble() function instead of the end after | ||
35 | an update. | ||

8 | CVE-2019-7577: Fix a buffer overread in MS_ADPCM_decode | ||
9 | If RIFF/WAV data chunk length is shorter then expected for an audio | ||
10 | format defined in preceeding RIFF/WAV format headers, a buffer | ||
11 | overread can happen. | ||
12 | |||
13 | This patch fixes it by checking a MS ADPCM data to be decoded are not | ||
14 | past the initialized buffer. | ||

28 | CVE-2019-7577: Fix a buffer overread in MS_ADPCM_nibble and MS_ADPCM_decode | ||
29 | If a chunk of RIFF/WAV file with MS ADPCM encoding contains an invalid | ||
30 | predictor (a valid predictor's value is between 0 and 6 inclusive), | ||
31 | a buffer overread can happen when the predictor is used as an index | ||
32 | into an array of MS ADPCM coefficients. | ||
33 | |||
34 | The overead happens when indexing MS_ADPCM_state.aCoeff[] array in | ||
35 | MS_ADPCM_decode() and later when dereferencing a coef pointer in | ||
36 | MS_ADPCM_nibble(). | ||
37 | |||
38 | This patch fixes it by checking the MS ADPCM predictor values fit | ||
39 | into the valid range. | ||

8 | CVE-2019-7635: Reject BMP images with pixel colors out the palette | ||
9 | If a 1-, 4-, or 8-bit per pixel BMP image declares less used colors | ||
10 | than the palette offers an SDL_Surface with a palette of the indicated | ||
11 | number of used colors is created. If some of the image's pixel | ||
12 | refer to a color number higher then the maximal used colors, a subsequent | ||
13 | bliting operation on the surface will look up a color past a blit map | ||
14 | (that is based on the palette) memory. I.e. passing such SDL_Surface | ||
15 | to e.g. an SDL_DisplayFormat() function will result in a buffer overread in | ||
16 | a blit function. | ||
17 | |||
18 | This patch fixes it by validing each pixel's color to be less than the | ||
19 | maximal color number in the palette. A validation failure raises an | ||
20 | error from a SDL_LoadBMP_RW() function. | ||

8 | CVE-2019-7637: Fix in integer overflow in SDL_CalculatePitch | ||
9 | If a too large width is passed to SDL_SetVideoMode() the width travels | ||
10 | to SDL_CalculatePitch() where the width (e.g. 65535) is multiplied by | ||
11 | BytesPerPixel (e.g. 4) and the result is stored into Uint16 pitch | ||
12 | variable. During this arithmetics an integer overflow can happen (e.g. | ||
13 | the value is clamped as 65532). As a result SDL_Surface with a pitch | ||
14 | smaller than width * BytesPerPixel is created, too small pixel buffer | ||
15 | is allocated and when the SDL_Surface is processed in SDL_FillRect() | ||
16 | a buffer overflow occurs. | ||
17 | |||
18 | This can be reproduced with "./graywin -width 21312312313123213213213" | ||
19 | command. | ||
20 | |||
21 | This patch fixes is by using a very careful arithmetics in | ||
22 | SDL_CalculatePitch(). If an overflow is detected, an error is reported | ||
23 | back as a special 0 value. We assume that 0-width surfaces do not | ||
24 | occur in the wild. Since SDL_CalculatePitch() is a private function, | ||
25 | we can change the semantics. | ||

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

10 | Petr Pisar | ||
11 | |||
12 | The reproducer has these data in BITMAPINFOHEADER: | ||
13 | |||
14 | biSize = 40 | ||
15 | biBitCount = 8 | ||
16 | biClrUsed = 131075 | ||
17 | |||
18 | 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. | ||
