CVE-2026-46602: CWE-789: Memory Allocation with Excessive Size Value in golang.org/x/image golang.org/x/image/tiff
The TIFF decoder does not set a limit on the size of tiles in tiled images, permitting a malicious or corrupt image containing a very large tile to cause unbounded memory consumption.
AI Analysis
Technical Summary
CVE-2026-46602 is a memory allocation vulnerability (CWE-789) in the TIFF decoder of the golang.org/x/image/tiff package. The decoder fails to limit the size of tiles in tiled TIFF images, enabling an attacker to craft an image with an excessively large tile size. When processed, this can cause the application to consume unbounded amounts of memory, potentially leading to denial of service. The vulnerability affects all versions before 0.43.0. There is currently no vendor-provided patch or official remediation guidance.
Potential Impact
The vulnerability can cause unbounded memory consumption during TIFF image decoding, which may lead to denial of service conditions due to resource exhaustion. There is no indication of confidentiality or integrity impact. 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. Until a fix is available, users should avoid processing untrusted or potentially malicious TIFF images with tiled data using affected versions of golang.org/x/image/tiff.
