PatchTheCVECVE-2023-29408: The TIFF decoder does not place a limit on the size of compressed tile data
CVE-2023-29408 is a medium-severity flaw (CVSS 6.5) affecting image, fedora. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
The TIFF decoder does not place a limit on the size of compressed tile 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, consuming excessive memory and CPU.
Why this priority
- No elevated risk signals yet
A fixed release or distro patch exists.
