{"cve":"CVE-2026-70652","nvd":{"published":"2026-08-20T21:17:08.270","modified":"2026-10-26T10:10:00.140","status":"Deferred","description":"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.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:L/VI:N/VA:L/SC:N/SI:N/SA:N","score":2.0},"cvss_v3":null,"cwes":["CWE-126"],"references":["https://github.com/libvips/libvips/commit/cff17794f0698a4f47c74bb31c9700b2c83252a8","https://github.com/libvips/libvips/pull/5039","https://github.com/libvips/libvips/releases/tag/v8.18.3","https://github.com/libvips/libvips/security/advisories/GHSA-h27h-jf9v-m8rg"],"products":[],"source":"nvd","synced_at":"2026-10-26T10:28:23.151169805+00:00"},"epss":{"cve":"CVE-2026-70652","score":0.00142,"percentile":0.03441,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
