Amazon Linux 2 : libtiff, --advisory ALAS2-2025-3019 (ALAS-2025-3019)

medium Nessus Plugin ID 270516

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of libtiff installed on the remote host is prior to 4.0.3-35. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2025-3019 advisory.

 Multiple potential integer overflow in tiffcp.c in libtiff <= 4.5.1 can allow remote attackers to cause a denial of service (application crash) or possibly execute an arbitrary code via a crafted tiff image which triggers a heap-based buffer overflow. (CVE-2023-40745)

 A vulnerability was identified in LibTIFF 4.7.0. This issue affects the function May of the file tiffcrop.c of the component tiffcrop. The manipulation leads to memory corruption. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. (CVE-2025-8961)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update libtiff' or or 'yum update --advisory ALAS2-2025-3019' to update your system.
