medium Nessus Plugin ID 266160

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 a vulnerability as referenced in the ALAS2-2025-3004 advisory.

A flaw has been found in LibTIFF 4.7.0. This affects the function
_TIFFmallocExt/_TIFFCheckRealloc/TIFFHashSetNew/InitCCITTFax3 of the file tools/tiffcmp.c of the component tiffcmp. Executing manipulation can lead to memory leak. The attack is restricted to local execution. The exploit has been published and may be used. This patch is called ed141286a37f6e5ddafb5069347ff5d587e7a4e0.
It is best practice to apply a patch to resolve this issue. (CVE-2025-9165)

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

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