CVE-2023-1916
Published: 10 April 2023
A flaw was found in tiffcrop, a program distributed by the libtiff package. A specially crafted tiff file can lead to an out-of-bounds read in the extractImageSection function in tools/tiffcrop.c, resulting in a denial of service and limited information disclosure. This issue affects libtiff versions 4.x.
Notes
| Author | Note |
|---|---|
| mdeslaur | low security impact as it is a denial of service in a command- line tool only, marking as low priority |
| ccdm94 | As of 2023-08-22, the fix for this issue seems to have not been merged (https://gitlab.com/libtiff/libtiff/-/merge_requests/476). |
| mdeslaur | There is a new merge request here: https://gitlab.com/libtiff/libtiff/-/merge_requests/535 Since the tiffcrop tool has been removed, the merge request will go nowhere, but can likely be used to fix previous releases. |
