NewStart CGSL MAIN 7.02 : libtiff Multiple Vulnerabilities (NS-SA-2026-0088)

low Nessus Plugin ID 343590

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 7.02, has libtiff packages installed that are affected by multiple vulnerabilities:

- 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. This attack is characterized by high complexity. It is indicated that the exploitability is difficult. The exploit has been published and may be used. There is ongoing doubt regarding the real existence of this vulnerability. This patch is called ed141286a37f6e5ddafb5069347ff5d587e7a4e0. It is best practice to apply a patch to resolve this issue. A researcher disputes the security impact of this issue, because this is a memory leak on a command line tool that is about to exit anyway. In the reply the project maintainer declares this issue as a simple 'bug' when leaving the command line tool and (...) not a security issue at all. (CVE-2025-9165)

- A null pointer dereference flaw was found in Libtiff via `tif_dirinfo.c`. This issue may allow an attacker to trigger memory allocation failures through certain means, such as restricting the heap space size or injecting faults, causing a segmentation fault. This can cause an application crash, eventually leading to a denial of service. (CVE-2024-7006)

- A vulnerability was found in LibTIFF up to 4.7.0. It has been declared as problematic. Affected by this vulnerability is the function t2p_read_tiff_init of the file tools/tiff2pdf.c of the component fax2ps. The manipulation leads to null pointer dereference. The attack needs to be approached locally. The complexity of an attack is rather high. The exploitation appears to be difficult. The patch is named 2ebfffb0e8836bfb1cd7d85c059cd285c59761a4. It is recommended to apply a patch to fix this issue.
(CVE-2024-13978)

- A vulnerability classified as problematic was found in libtiff 4.6.0. This vulnerability affects the function PS_Lvl2page of the file tools/tiff2ps.c of the component tiff2ps. The manipulation leads to null pointer dereference. It is possible to launch the attack on the local host. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The name of the patch is 6ba36f159fd396ad11bf6b7874554197736ecc8b. It is recommended to apply a patch to fix this issue. One of the maintainers explains, that [t]his error only occurs if DEFER_STRILE_LOAD (defer-strile-load:BOOL=ON) or TIFFOpen( .. rD) option is used. (CVE-2025-8534)

- A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations, potentially causing a denial of service (application crash) or arbitrary code execution. (CVE-2026-4775)

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

Solution

Upgrade the vulnerable CGSL libtiff packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
