Libtiff · Libtiff · CVE-2023-0797
**Name of the Vulnerable Software and Affected Versions**
LibTIFF version 4.4.0
**Description**
The issue is related to an out-of-bounds read in the `tiffcrop` function, specifically in `libtiff/tif unix.c:368`, which can be invoked by `tools/tiffcrop.c:2903` and `tools/tiffcrop.c:6921`. This allows attackers to cause a denial-of-service via a crafted tiff file. The problem is associated with a buffer read beyond its boundaries in memory, potentially leading to a service disruption.
**Recommendations**
For LibTIFF version 4.4.0, users who compile libtiff from sources can apply the fix available with commit `afaabc3e`. As a temporary workaround, consider restricting the use of the `tiffcrop` function until a patch is available.
