GHSA-2v8p-fqpx-2q3w: jxl-oxide: integer subtraction overflow panic in cluster_from_table via crafted JXL input (DoS)
A logic bug in the jxl-oxide crate's decode_simple_table_slow function can cause an integer subtraction overflow when decoding certain Modular JXL images. This overflow triggers a panic if overflow checks are enabled, leading to a denial of service (DoS) by crashing the application. The issue affects all builds with overflow checks enabled, including debug builds and any release builds configured with overflow checks. No memory corruption or code execution is possible as the panic occurs before unsafe code is reached.
AI Analysis
Technical Summary
The vulnerability in jxl-oxide arises from an integer arithmetic overflow in the decode_simple_table_slow function when processing a Modular image with a specific MA tree structure. This overflow causes a panic under Rust's overflow-checking mode, crashing any application that processes untrusted JXL data via JxlImage::render_frame or equivalent calls. The flaw leads to denial of service but does not result in memory corruption or other security impacts. It affects all versions prior to 0.11.3 when overflow checks are enabled.
Potential Impact
Denial of service due to application crash when processing crafted JXL images with the affected jxl-oxide versions and overflow checks enabled. There is no impact on confidentiality or integrity, and no memory corruption occurs.
Mitigation Recommendations
A fix is available in jxl-oxide version 0.11.3. Users should upgrade to version 0.11.3 or later to resolve this issue. Until then, avoid processing untrusted JXL data with builds that have overflow checks enabled.
