{"apiVersion":"1.0","identifier":"CVE-2026-70652","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.","publishedAt":"2026-08-20T21:17:08","lastModifiedAt":"2026-08-21T22:16:43","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-70652","cvssScore":2,"cvssVector":"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","epssProbability":0.00114,"riskScore":0.2,"affectedProduct":"libvips","affectedVersions":"<8.18.3","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-70652","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-70652","en":"https://www.redsauce.net/en/cves/CVE-2026-70652","fr":"https://www.redsauce.net/fr/cves/CVE-2026-70652","pt":"https://www.redsauce.net/pt/cves/CVE-2026-70652","de":"https://www.redsauce.net/de/cves/CVE-2026-70652","sk":"https://www.redsauce.net/sk/cves/CVE-2026-70652","el":"https://www.redsauce.net/el/cves/CVE-2026-70652"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-70652"}}
