Name of the Vulnerable Software and Affected Versions libtiff library version 4.3.0

Description A heap buffer overflow in the ExtractImageSection function in tiffcrop.c allows an attacker to trigger unsafe or out of bounds memory access via a crafted TIFF image file, which could result in an application crash, potential information disclosure, or any other context-dependent impact.

Recommendations For libtiff library version 4.3.0, consider updating to a newer version that contains a fix for this issue, as using a crafted TIFF image file could lead to application crash or information disclosure. As a temporary workaround, consider restricting the use of the ExtractImageSection function in tiffcrop.c until a patch is available. Avoid using the tiffcrop.c component with untrusted TIFF image files until the issue is resolved.
