Title
Excessive resource consumption in PackBits decompression in golang.org/x/image/tiff
Summary
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.
Severity
No CVSS data available.
CWE
  • CWE-770 - Allocation of Resources Without Limits or Throttling
