Prior to version 1.1.0, a crafted H.265 bitstream with large SPS dimensions and 16-bit bit depth causes a signed integer overflow in `de265_image_get_buffer()` (`libde265/image.cc:128`). The overflow wraps the plane allocation size to a small value (~1 KB), but the subsequent `fill_image()` call computes the real size using `size_t`, writing ~4 GB into the undersized heap buffer. Version 1.1.0 patches the issue."}], "lastModified": "2026-06-26T19:17:38.463", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:struktur:libde265:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "B8290F95-BF35-4C0A-A314-D8B0CBB5760E", "versionEndExcluding": "1.1.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
