jxl-oxide: integer subtraction overflow panic in cluster_from_table via crafted JXL input (DoS)
GitHub lists this reviewed advisory for jxl-modular. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.
01 / Meaning
Why it matters
Published affected context helps an owner decide what evidence to gather. This report has not examined your application.
6.2 medium
GitHub source severity; exploitability and local consequence require separate evidence.

The affected context

jxl-modular
source listed<= 0.11.2
### 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.
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
