Attackers can supply a password longer than 127 bytes through applications using the libpoppler, libpoppler-glib or C++ API to overflow the K1 and E buffers, crashing the process or corrupting memory.","categories":["Unclassified"],"product":"poppler","vendor":"freedesktop","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-107705","source_modified_at":"2026-10-14T16:05:29.301Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"poppler","vendor":"freedesktop","versions":[{"version":"0.42.0","lessThanOrEqual":"26.10.0","status":"affected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":8.3,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00328,"percentile":0.24641,"score_date":"2026-10-23"},"published_at":"2026-10-08T19:51:12.884Z","modified_at":"2026-10-14T16:05:29.301Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-107705","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T16:05:29.301Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-107705","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://gitlab.freedesktop.org/poppler/poppler/-/work_items/1814","tags":["issue-tracking"]},{"source":"CVE List","url":"https://gitlab.freedesktop.org/poppler/poppler/-/merge_requests/2398","tags":["patch"]},{"source":"CVE List","url":"https://gitlab.freedesktop.org/poppler/poppler/-/blob/poppler-26.10.0/poppler/Decrypt.cc#L1767","tags":["technical-description"]},{"source":"CVE List","url":"https://gitlab.freedesktop.org/poppler/poppler","tags":["product"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/poppler-0.42.0-through-26.10.0-stack-buffer-overflow-via-decrypt-revision6hash","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-14T14:50:23.158769Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T16:05:29.301Z","content_hash":"723229261e43e186b50df04331ff5b0b84a2f7ec2fa30e3ac5c8a419be01bc7f"}}
