CVE-2023-45661

stbimage is a single file MIT licensed library for processing images. A crafted image file may trigger out of bounds memcpy read in stbigifloadnext. This happens because twoback points to a memory address lower than the start of the buffer out. This issue may be used to leak internal memory...

CVE-2023-45662

stbimage is a single file MIT licensed library for processing images. When stbisetflipverticallyonload is set to TRUE and reqcomp 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 memc...

CVE-2023-45675

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 the len read in startdecoder is -1 and len + 1 becomes 0 when passed to setupmalloc. The setupmalloc behaves...

Design/Logic Flaw

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...

Design/Logic Flaw

stbimage is a single file MIT licensed library for processing images. The stbigetn 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...

Out-of-bounds

stbimage is a single file MIT licensed library for processing images. When stbisetflipverticallyonload is set to TRUE and reqcomp 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 memc...

Null pointer dereference

stbimage is a single file MIT licensed library for processing images. If stbiloadgifmain in stbiloadgiffrommemory 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 stbiverticalflipslices with th...

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 the len read in startdecoder is -1 and len + 1 becomes 0 when passed to setupmalloc. The setupmalloc behaves...

CVE-2023-45678

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-2023-45661

stbimage is a single file MIT licensed library for processing images. A crafted image file may trigger out of bounds memcpy read in stbigifloadnext. This happens because twoback points to a memory address lower than the start of the buffer out. This issue may be used to leak internal memory...

CVE-2023-45666

stbimage is a single file MIT licensed library for processing images. It may look like stbiloadgifmain 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...

CVE-2023-45676

stbvorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger out of bounds write in f-vendori = get8packetf;. The root cause is an integer overflow in setupmalloc. A sufficiently large value in the variable sz overflows with sz+7 in and the negative...

Design/Logic Flaw

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...

Out-of-bounds

stbimage is a single file MIT licensed library for processing images. A crafted image file may trigger out of bounds memcpy read in stbigifloadnext. This happens because twoback points to a memory address lower than the start of the buffer out. This issue may be used to leak internal memory...

Double free

stbimage is a single file MIT licensed library for processing images. A crafted image file can trigger stbiloadgifmainoutofmem attempt to double-free the out variable. This happens in stbiloadgifmain because when the layers stride value is zero the behavior is implementation defined, but common...

CVE-2023-45677

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...

CVE-2023-45663

stbimage is a single file MIT licensed library for processing images. The stbigetn 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...

CVE-2023-45682

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-2023-45664

stbimage is a single file MIT licensed library for processing images. A crafted image file can trigger stbiloadgifmainoutofmem attempt to double-free the out variable. This happens in stbiloadgifmain because when the layers stride value is zero the behavior is implementation defined, but common...
