According to the versions of the libtiff package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

    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 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 was determined in LibTIFF up to 4.5.1. Affected by this issue is the function     readSeparateStripsetoBuffer of the file tools/tiffcrop.c of the component tiffcrop. The manipulation leads     to stack-based buffer overflow. Local access is required to approach this attack. The patch is identified     as 8a7a48d7a645992ca83062b3a1873c951661e2b3. It is recommended to apply a patch to fix this     issue.(CVE-2025-8851)

    A vulnerability was found in LibTIFF up to 4.7.0. It has been rated as critical. This issue affects the     function setrow of the file tools/thumbnail.c. The manipulation leads to buffer overflow. An attack has to     be approached locally. The patch is named e8c9d6c616b19438695fd829e58ae4fde5bfbc22. It is recommended to     apply a patch to fix this issue. This vulnerability only affects products that are no longer supported by     the maintainer.(CVE-2025-8177)

    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 flaw was found in Libtiff. This vulnerability is a 'write-what-where' condition, triggered when the     library processes a specially crafted TIFF image file. By providing an abnormally large image height value     in the file's metadata, an attacker can trick the library into writing attacker-controlled color data to     an arbitrary memory location. This memory corruption can be exploited to cause a denial of service     (application crash) or to achieve arbitrary code execution with the permissions of the     user.(CVE-2025-9900)
