CVE-2026-46599: CWE-770: Allocation of Resources Without Limits or Throttling in golang.org/x/image golang.org/x/image/tiff
The TIFF decoder does not place a limit on the size of PackBits-compressed data. A maliciously-crafted image can exploit this to cause a small image (both in terms of pixel width/height and encoded size) to make the decoder decode large amounts of compressed data.
AI Analysis
Technical Summary
The vulnerability in golang.org/x/image/tiff arises from the TIFF decoder's failure to impose limits on the size of PackBits-compressed data. An attacker can craft a TIFF image that is small in pixel dimensions and encoded size but decompresses into a very large amount of data, potentially causing resource exhaustion due to uncontrolled allocation during decoding. This is classified under CWE-770: Allocation of Resources Without Limits or Throttling. No CVSS score or remediation details are currently available.
Potential Impact
This vulnerability can lead to resource exhaustion on systems decoding malicious TIFF images, potentially causing denial of service or application instability. Since the decoder does not limit decompression size, it may consume excessive memory or CPU resources. There are no reports of active exploitation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should consider restricting or validating TIFF image inputs from untrusted sources to mitigate potential resource exhaustion.
