OSV-2022-725: Heap-buffer-overflow in jxl::N_EMU128::WriteToU8Stage::ProcessRow
A heap-buffer-overflow vulnerability exists in the libjxl library within the jxl::N_EMU128::WriteToU8Stage::ProcessRow function. This issue was reported by OSS-Fuzz and involves an out-of-bounds write on the heap during image processing. Multiple versions of libjxl up to and including 0.12.0 are affected. No official patch or remediation information is provided in the available data.
AI Analysis
Technical Summary
The vulnerability is a heap-buffer-overflow triggered in the function jxl::N_EMU128::WriteToU8Stage::ProcessRow of the libjxl library, as identified by OSS-Fuzz. The crash involves a write operation outside the allocated heap buffer, which may lead to memory corruption. The issue occurs during the processing of image data in the LowMemoryRenderPipeline component. Affected versions include a wide range of releases from 0.8.0 through 0.12.0, including snapshots. No CVSS score or detailed impact metrics are provided, and no vendor advisory or patch information is available.
Potential Impact
Heap-buffer-overflow vulnerabilities can lead to memory corruption, which may cause application crashes or potentially enable arbitrary code execution depending on the context of exploitation. However, no known exploits in the wild have been reported for this vulnerability. The impact is limited to applications using the affected versions of libjxl for image processing.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider avoiding use of affected libjxl versions or apply any available updates from the libjxl project. Monitor official libjxl channels for patches addressing this issue.
