AlmaLinux 9.6 [TuxCare] Security Update: libtiff / libtiff-devel / libtiff-static / libtiff-tools Multiple Vulnerabilities (ALMALINUX9.6:CLSA-2026:1776349106)

medium Nessus Plugin ID 360004

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1776349106 advisory.

- A stack overflow was discovered in the _TIFFVGetField function of Tiffsplit v4.4.0. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted TIFF file parsed by the tiffsplit or tiffcrop utilities. (CVE-2022-34526)

- 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.
(CVE-2023-1916)

- A null pointer dereference issue was found in Libtiff's tif_dir.c file. This issue may allow an attacker to pass a crafted TIFF image file to the tiffcp utility which triggers a runtime error that causes undefined behavior. This will result in an application crash, eventually leading to a denial of service.
(CVE-2023-2908)

- A heap-buffer-overflow vulnerability was found in LibTIFF, in extractImageSection() at tools/tiffcrop.c:7916 and tools/tiffcrop.c:7801. This flaw allows attackers to cause a denial of service via a crafted tiff file. (CVE-2023-3164)

- An out-of-memory flaw was found in libtiff. Passing a crafted tiff file to TIFFOpen() API may allow a remote attacker to cause a denial of service via a craft input with size smaller than 379 KB.
(CVE-2023-6277)

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

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.6:CLSA-2026:1776349106.
