Média
| Vetor | AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
libtiff versions 4.x
Description
The issue is related to a flaw in the
extractImageSection function of the libtiff library, which can cause an out-of-bounds read in memory. This can lead to a denial of service and limited information disclosure when a specially crafted TIFF file is processed. The extractImageSection function in tools/tiffcrop.c is specifically affected.Recommendations
For libtiff versions 4.x, improved checks have been implemented to address the issue. As a temporary workaround, consider restricting the use of the
extractImageSection function in tools/tiffcrop.c until the improved checks are applied. Additionally, avoid processing specially crafted TIFF files with the affected libtiff versions to minimize the risk of exploitation.Exploit
