Summary
jxl-oxide: integer subtraction overflow panic in cluster_from_table via crafted JXL input (DoS)
Details

Summary

Logic bug in decode_simple_table_slow may cause integer arithmetic overflow when decoding Modular image with certain kind of MA tree, which may panic with overflow-checks enabled.

Impact

Denial of service: any application passing untrusted JXL data to JxlImage::render_frame (or equivalent) can be crashed. Affects all builds with overflow checks enabled, which includes debug builds and any release build that sets overflow-checks = true in Cargo.toml or [profile.*].

No memory corruption is possible — the panic fires before any unsafe code is reached.

Severity
6.2 (Medium)
CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
