CVE-2018-16981 2 Debian, Nothings 2 Debian Linux, Stb Image.h 2024-09-16 8.8 High
stb stb_image.h 2.19, as used in catimg, Emscripten, and other products, has a heap-based buffer overflow in the stbi__out_gif_code function.
CVE-2023-45661 1 Nothings 1 Stb Image.h 2024-09-12 6.5 Medium
stb_image is a single file MIT licensed library for processing images. A crafted image file may trigger out of bounds memcpy read in `stbi__gif_load_next`. This happens because two_back points to a memory address lower than the start of the buffer out. This issue may be used to leak internal memory allocation information.
CVE-2023-45662 1 Nothings 1 Stb Image.h 2024-09-12 6.5 Medium
stb_image is a single file MIT licensed library for processing images. When `stbi_set_flip_vertically_on_load` is set to `TRUE` and `req_comp` is set to a number that doesn’t match the real number of components per pixel, the library attempts to flip the image vertically. A crafted image file can trigger `memcpy` out-of-bounds read because `bytes_per_pixel` used to calculate `bytes_per_row` doesn’t match the real image array dimensions.
CVE-2023-45663 1 Nothings 1 Stb Image.h 2024-09-12 5.3 Medium
stb_image is a single file MIT licensed library for processing images. The stbi__getn function reads a specified number of bytes from context (typically a file) into the specified buffer. In case the file stream points to the end, it returns zero. There are two places where its return value is not checked: In the `stbi__hdr_load` function and in the `stbi__tga_load` function. The latter of the two is likely more exploitable as an attacker may also control the size of an uninitialized buffer.
CVE-2023-45664 1 Nothings 1 Stb Image.h 2024-09-12 7.3 High
stb_image is a single file MIT licensed library for processing images. A crafted image file can trigger `stbi__load_gif_main_outofmem` attempt to double-free the out variable. This happens in `stbi__load_gif_main` because when the `layers * stride` value is zero the behavior is implementation defined, but common that realloc frees the old memory and returns null pointer. Since it attempts to double-free the memory a few lines below the first “free”, the issue can be potentially exploited only in a multi-threaded environment. In the worst case this may lead to code execution.
CVE-2023-45666 1 Nothings 1 Stb Image.h 2024-09-12 7.3 High
stb_image is a single file MIT licensed library for processing images. It may look like `stbi__load_gif_main` doesn’t give guarantees about the content of output value `*delays` upon failure. Although it sets `*delays` to zero at the beginning, it doesn’t do it in case the image is not recognized as GIF and a call to `stbi__load_gif_main_outofmem` only frees possibly allocated memory in `*delays` without resetting it to zero. Thus it would be fair to say the caller of `stbi__load_gif_main` is responsible to free the allocated memory in `*delays` only if `stbi__load_gif_main` returns a non null value. However at the same time the function may return null value, but fail to free the memory in `*delays` if internally `stbi__convert_format` is called and fails. Thus the issue may lead to a memory leak if the caller chooses to free `delays` only when `stbi__load_gif_main` didn’t fail or to a double-free if the `delays` is always freed
CVE-2023-45667 1 Nothings 1 Stb Image.h 2024-09-12 5.3 Medium
stb_image is a single file MIT licensed library for processing images. If `stbi__load_gif_main` in `stbi_load_gif_from_memory` fails it returns a null pointer and may keep the `z` variable uninitialized. In case the caller also sets the flip vertically flag, it continues and calls `stbi__vertical_flip_slices` with the null pointer result value and the uninitialized `z` value. This may result in a program crash.
CVE-2023-45675 1 Nothings 1 Stb Vorbis.c 2024-09-12 6.5 Medium
stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger out of bounds write in `f->vendor[len] = (char)'\0';`. The root cause is that if the len read in `start_decoder` is `-1` and `len + 1` becomes 0 when passed to `setup_malloc`. The `setup_malloc` behaves differently when `f->alloc.alloc_buffer` is pre-allocated. Instead of returning `NULL` as in `malloc` case it shifts the pre-allocated buffer by zero and returns the currently available memory block. This issue may lead to code execution.
CVE-2023-45676 1 Nothings 1 Stb Vorbis.c 2024-09-12 7.3 High
stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger out of bounds write in `f->vendor[i] = get8_packet(f);`. The root cause is an integer overflow in `setup_malloc`. A sufficiently large value in the variable `sz` overflows with `sz+7` in and the negative value passes the maximum available memory buffer check. This issue may lead to code execution.
CVE-2023-45677 1 Nothings 1 Stb Vorbis.c 2024-09-12 7.3 High
stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger out of bounds write in `f->vendor[len] = (char)'\0';`. The root cause is that if `len` read in `start_decoder` is a negative number and `setup_malloc` successfully allocates memory in that case, but memory write is done with a negative index `len`. Similarly if len is INT_MAX the integer overflow len+1 happens in `f->vendor = (char*)setup_malloc(f, sizeof(char) * (len+1));` and `f->comment_list[i] = (char*)setup_malloc(f, sizeof(char) * (len+1));`. This issue may lead to code execution.
CVE-2023-45678 1 Nothings 1 Stb Vorbis.c 2024-09-12 6.5 Medium
stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger out of buffer write in `start_decoder` because at maximum `m->submaps` can be 16 but `submap_floor` and `submap_residue` are declared as arrays of 15 elements. This issue may lead to code execution.
CVE-2023-45679 1 Nothings 1 Stb Vorbis.c 2024-09-12 7.3 High
stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger memory allocation failure in `start_decoder`. In that case the function returns early, but some of the pointers in `f->comment_list` are left initialized and later `setup_free` is called on these pointers in `vorbis_deinit`. This issue may lead to code execution.
CVE-2023-45682 1 Nothings 1 Stb Vorbis.c 2024-09-12 5.3 Medium
stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger out of bounds read in `DECODE` macro when `var` is negative. As it can be seen in the definition of `DECODE_RAW` a negative `var` is a valid value. This issue may be used to leak internal memory allocation information.
CVE-2023-45680 1 Nothings 1 Stb Vorbis.c 2024-09-11 5.3 Medium
stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger memory allocation failure in `start_decoder`. In that case the function returns early, the `f->comment_list` is set to `NULL`, but `f->comment_list_length` is not reset. Later in `vorbis_deinit` it tries to dereference the `NULL` pointer. This issue may lead to denial of service.
CVE-2023-43281 1 Nothings 1 Stb Image.h 2024-09-11 6.5 Medium
Double Free vulnerability in Nothings Stb Image.h v.2.28 allows a remote attacker to cause a denial of service via a crafted file to the stbi_load_gif_main function.
CVE-2019-20056 1 Nothings 1 Stb Image.h 2024-08-05 6.5 Medium
stb_image.h (aka the stb image loader) 2.23, as used in libsixel and other products, has an assertion failure in stbi__shiftsigned.
CVE-2019-19777 2 Libsixel Project, Nothings 2 Libsixel, Stb Image.h 2024-08-05 8.8 High
stb_image.h (aka the stb image loader) 2.23, as used in libsixel and other products, has a heap-based buffer over-read in stbi__load_main.
CVE-2020-6619 1 Nothings 1 Stb Truetype.h 2024-08-04 8.8 High
stb stb_truetype.h through 1.22 has an assertion failure in stbtt__buf_seek.
CVE-2020-6620 1 Nothings 1 Stb Truetype.h 2024-08-04 8.8 High
stb stb_truetype.h through 1.22 has a heap-based buffer over-read in stbtt__buf_get8.
CVE-2020-6622 1 Nothings 1 Stb Truetype.h 2024-08-04 8.8 High
stb stb_truetype.h through 1.22 has a heap-based buffer over-read in stbtt__buf_peek8.
