  "details" : [ "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.", "A flaw was found in the `golang.org/x/image/tiff` package's TIFF decoder. This vulnerability occurs because the decoder does not properly limit the size of PackBits-compressed data. A remote attacker could exploit this by providing a maliciously-crafted image, leading to the decoder processing excessive amounts of data. This can result in a Denial of Service (DoS) due to resource exhaustion, even with a small input image." ],
  "statement" : "Red Hat rates this issue as Moderate with RH CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). A flaw was found in golang.org/x/image/tiff where the TIFF decoder does not limit the size of PackBits-compressed data. A maliciously crafted TIFF image with small declared dimensions can cause the decoder to process disproportionately large amounts of compressed data, leading to resource exhaustion. Exploitation requires user interaction (opening a crafted TIFF file). Most Red Hat products that bundle golang.org/x/image do not process untrusted TIFF input in their supported execution paths.",
