Medium [CVE-2026-70652] Information disclosure or denial of service via heap buffer over-read when processing JPEGs with gain maps
CVE-2026-70652Source published Source updated
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 vips_foreign_save_uhdr_set_raw_hdr 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. Moderate: This flaw in libvips, when built with libultrahdr support, could lead to information disclosure or a denial of service. Exploitation requires processing a specially crafted JPEG with gain map data, which may not be a default or common operation in all Red Hat environments.…
