CVE-2026-46602: CWE-789: Memory Allocation with Excessive Size Value in golang.org/x/image golang.org/x/image/tiff
A vulnerability in the golang.org/x/image/tiff package allows unbounded memory consumption due to the TIFF decoder not limiting the size of tiles in tiled images. This can be triggered by a malicious or corrupt TIFF image containing an excessively large tile. The issue affects versions prior to 0.43.0.
AI Analysis
Technical Summary
CVE-2026-46602 is a memory allocation vulnerability (CWE-789) in the golang.org/x/image/tiff package. The TIFF decoder fails to impose limits on tile sizes in tiled TIFF images, which can lead to unbounded memory allocation when processing a malicious or corrupted image with very large tiles. This can cause excessive memory consumption, potentially impacting application stability or availability. The vulnerability affects all versions before 0.43.0 of the package. No CVSS score or official remediation level has been published yet.
Potential Impact
Unbounded memory consumption caused by processing a malicious or corrupted TIFF image with very large tiles may lead to denial of service through resource exhaustion. There is no indication of code execution or data corruption beyond memory exhaustion. No known exploits are reported in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Users should monitor golang.org/x/image project updates for an official fix in versions 0.43.0 or later. Until a fix is available, avoid processing untrusted TIFF images or implement external memory usage limits when decoding TIFF images.
