{"id":"JLSEC-2026-122","details":"Integer overflow in libaom internal function `img_alloc_helper` can lead to heap buffer overflow. This function can be reached via 3 callers:\n\n  - Calling `aom_img_alloc()` with a large value of the `d_w`, `d_h`, or align parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned `aom_image_t` struct may be invalid.\n  - Calling `aom_img_wrap()` with a large value of the `d_w`, `d_h`, or align parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned `aom_image_t` struct may be invalid.\n  - Calling `aom_img_alloc_with_border()` with a large value of the `d_w`, `d_h`, align, `size_align`, or border parameter may result in integer overflows in the calculations of buffer sizes and offsets and some fields of the returned `aom_image_t` struct may be invalid.","modified":"2026-07-25T18:23:53.945735374Z","published":"2026-04-16T23:30:44.982Z","upstream":["CVE-2024-5171"],"database_specific":{"sources":[{"id":"CVE-2024-5171","imported":"2026-07-17T21:11:44.773Z","modified":"2026-06-17T08:15:20.570Z","published":"2024-06-05T20:15:13.800Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2024-5171","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2024-5171","database_specific":{"status":"Modified"}}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://issues.chromium.org/issues/332382766"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/09/msg00024.html"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/6HYUEHZ35ZPY2EONVZCGO6LPT3AMLZCP/"},{"type":"WEB","url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/U5NRNCEYS246CYGOR32MF7OGKWOWER22/"}],"affected":[{"package":{"name":"libaom_jll","ecosystem":"Julia","purl":"pkg:julia/libaom_jll?uuid=a4ae2306-e953-59d6-aa16-d00cac43593b"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.11.0+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-122.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H/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"}]}
