libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, applications that define unusual custom libvips sources and use them to process untrusted uncompressed PPM images can trigger a max/min error in vipssourcereadtomemory in libvips/iofuncs/source.c. The function uses VIPSMAX instead of VIPSMIN when selecting the remaining read size, allowing up to 4032 bytes to be written beyond the allocated heap buffer and causing memory corruption or a process crash. This issue is fixed in version 8.18.3.

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, the old-style Radiance RLE decoder in libvips/foreign/radiance.c can process a repeat marker at the beginning of a scanline in scanlinereadold and read q[-1] before any prior pixel exists. A crafted Radiance image loaded through VipsForeignLoadRad can therefore disclose four bytes of adjacent heap data, most likely other image data. This issue is fixed in version 8.18.3.

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, libvips built without libtiff support but with ImageMagick support can overflow the combined frame height while loading a crafted multi-page TIFF through VipsForeignLoadMagick. The vulnerable calculations in libvips/foreign/magick6load.c and libvips/foreign/magick7load.c multiply the per-page Ysize by nframes without a checked bound, which can cause a heap buffer over-read and process crash. Most package-manager builds include libtiff and do not use this affected fallback path. This issue is fixed in version 8.18.3.

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, libvips built with libultrahdr support can incorrectly size an output buffer in libvips/foreign/uhdrsave.c within vipsforeignsaveuhdrsetrawhdr when a pipeline enlarges an incoming JPEG to a very large output before encoding a gain map through VipsForeignSaveUhdr. The undersized allocation can cause a heap buffer over-read that may disclose adjacent data or crash the process. This issue is fixed in version 8.18.3.

libvips is a fast image processing library with low memory needs. Prior to version 8.18.3, a crafted many-band TIFF processed through VipsForeignLoadTiff can evade scanline validation in libvips/iofuncs/image.c and cause an integer overflow in vipsimagesanity. The resulting buffer-region calculation can access attacker-controlled negative offsets in mmap-resident allocations, allowing reads or writes of other image data, possible data disclosure through uncompressed .v output, and likely process crashes. Remote code execution has not been demonstrated but cannot be ruled out. This issue is fixed in version 8.18.3.

libvips is a fast image processing library with low memory needs. The tiffload operation in libvips versions before and including 8.18.1 could incorrectly determine the number of channels in a JPEG or JPEG2000-encoded tile within a TIFF image, leading to a possible buffer overflow. This has been patched in version 8.18.2.

libvips is a fast image processing library with low memory needs. The EXIF decoder within libvips versions before and including 8.18.1 was not verifying the range of EXIF tag groups before passing data to libexif, leading to a possible null pointer dereference and crash. This has been patched in version 8.18.2.

libvips is a fast image processing library with low memory needs. On 32-bit systems in versions before and including 8.18.0, the gifload operation could incorrectly determine dimensions leading to an integer overflow. This has been patched in version 8.18.1.

libvips is a fast image processing library with low memory needs. The vipsload operation in versions before and including 8.18.0 could incorrectly determine image dimensions leading to an integer overflow and a subsequent heap-based buffer overflow. This has been patched in version 8.18.1.

A security vulnerability has been detected in libvips up to 8.18.2. The affected element is the function imminposvec of the file libvips/deprecated/vips7compat.c of the component nip2 Handler.

A vulnerability was determined in libvips up to 8.19.0. The affected element is the function vipssourcereadtomemory of the file libvips/iofuncs/source.c. This manipulation causes heap-based buffer overflow. It is possible to launch the attack on the local host. The attack's complexity is rated as high. The exploitability is described as difficult. The exploit has been publicly disclosed and may be utilized. Patch name: a56feecbe9ed66521d9647ec9fbcd2546eccd7ee. Applying a patch is the recommended action to fix this issue. The confirmation of the bugfix mentions: "[T]he impact of this is negligible, since this only affects custom seekable sources larger than 4 GiB (and the crash occurs in user code rather than libvips itself)."

libvips is a demand-driven, horizontally threaded image processing library. For versions 8.17.1 and below, when libvips is compiled with support for PDF input via poppler, the pdfload operation is affected by a buffer read overflow when parsing the header of a crafted PDF with a page that defines a width but not a height. Those using libvips compiled without support for PDF input are unaffected as well as thosewith support for PDF input via PDFium. This issue is fixed in version 8.17.2. A workaround for those affected is to block the VipsForeignLoadPdf operation via vipsoperationblockset, which is available in most language bindings, or to set VIPSBLOCKUNTRUSTED environment variable at runtime, which will block all untrusted loaders including PDF input via poppler.

In libvips before 8.6.3, a NULL function pointer dereference vulnerability was found in the vipsregiongenerate function in region.c, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted image file. This occurs because of a race condition involving a failed delayed load and other worker threads.
