stb_vorbis buffer error vulnerability

stbvorbis is an open source audio decoder for decoding ogg vorbis files. A security vulnerability exists in stbvorbis, which stems from the fact that a carefully crafted file may trigger a buffer write in "startdecoder", because "m-submaps" can be at most 16, but "submapfloor" and "submapresidue"...

CVE-2023-45682 Wild address read in vorbis_decode_packet_rest in stb_vorbis

stbvorbis 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 DECODERAW a negative var is a valid value. This issue may be used to leak internal memory...

CVE-2023-45682

CVE-2023-45682 affects stb_vorbis (used by stb_vorbis.c, MIT license). A crafted Vorbis file may trigger an out-of-bounds read in the DECODE macro when var is negative, because DECODE_RAW allows negative values, potentially leaking internal memory allocation information. Multiple connected adviso...

CVE-2023-45681

stbvorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger memory write past an allocated heap buffer in startdecoder. The root cause is a potential integer overflow in sizeofchar f-commentlistlength which may make setupmalloc allocate less memory...

CVE-2023-45680 Null pointer dereference in vorbis_deinit in stb_vorbis

stbvorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger memory allocation failure in startdecoder. In that case the function returns early, the f-commentlist is set to NULL, but f-commentlistlength is not reset. Later in vorbisdeinit it tries to...

CVE-2023-45679

CVE-2023-45679 affects stb_vorbis (a single-file MIT licensed library) used by SDL2_sound. A crafted Vorbis file can trigger a memory allocation failure in start_decoder, causing early return while some f->comment_list pointers remain initialized; later vorbis_deinit calls setup_free on them, ...

CVE-2023-45679 Attempt to free an uninitialized memory pointer in vorbis_deinit in stb_vorbis

stbvorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger memory allocation failure in startdecoder. In that case the function returns early, but some of the pointers in f-commentlist are left initialized and later setupfree is called on these...

CVE-2023-45678 Off-by-one heap buffer write in start_decoder in stb_vorbis

stbvorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger out of buffer write in startdecoder because at maximum m-submaps can be 16 but submapfloor and submapresidue are declared as arrays of 15 elements. This issue may lead to code execution...

CVE-2023-45678

CVE-2023-45678 affects the stb_vorbis library (open-source Ogg Vorbis decoder). The root cause described in multiple sources is an out-of-bounds write in start_decoder where m->submaps can be up to 16, but submap_floor and submap_residue are declared as 15-element arrays, creating a potential ...

CVE-2023-45677

CVE-2023-45677 affects stb_vorbis used by SDL2_sound/stb_vorbis.c. A crafted file can trigger a heap out-of-bounds write via f->vendor[len] = (char) '\0' with a negative len during start_decoder, and an integer overflow when len is INT_MAX during allocation of f->vendor and comment_list[i]....

CVE-2023-45677 Heap buffer out of bounds write in start_decoder in stb_vorbis

stbvorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger out of bounds write in f-vendorlen = char'\0';. The root cause is that if len read in startdecoder is a negative number and setupmalloc successfully allocates memory in that case, but memor...
