There exists one heap buffer overflow in _TIFFmemcpy in tif_unix.c in libtiff 4.0.10, which allows an attacker to cause a denial-of-service through a crafted tiff file.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libtiff: Heap-based buffer overflow in TIFF2PDF tool (CVE-2020-35524)

  - libtiff: heap-buffer overflow via extractContigSamplesBytes() at /libtiff/tools/tiffcrop.c     (CVE-2023-25434)

  - tools/pal2rgb.c in pal2rgb in LibTIFF 4.0.9 allows remote attackers to cause a denial of service     (TIFFSetupStrips heap-based buffer overflow and application crash) or possibly have unspecified other     impact via a crafted TIFF file. (CVE-2017-17095)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

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

  - There exists one heap buffer overflow in _TIFFmemcpy in tif_unix.c in libtiff 4.0.10, which allows an     attacker to cause a denial-of-service through a crafted tiff file. (CVE-2020-18768)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

  - loadImage() in tools/tiffcrop.c in LibTIFF through 4.5.0 has a heap-based use after free via a crafted     TIFF image. (CVE-2023-26965)

  - A flaw was found in libtiff. A specially crafted tiff file can lead to a segmentation fault due to a     buffer overflow in the Fax3Encode function in libtiff/tif_fax3.c, resulting in a denial of service.
    (CVE-2023-3618)

  - LibTIFF is vulnerable to an integer overflow. This flaw allows 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 found in libtiff due to multiple potential integer overflows in raw2tiff.c. This flaw     allows remote attackers to cause a denial of service or possibly execute an arbitrary code via a crafted     tiff image, which triggers a heap-based buffer overflow. (CVE-2023-41175)

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4370-1 advisory.

  - There exists one heap buffer overflow in _TIFFmemcpy in tif_unix.c in libtiff 4.0.10, which allows an     attacker to cause a denial-of-service through a crafted tiff file. (CVE-2020-18768)

  - libtiff 4.5.0 is vulnerable to Buffer Overflow via /libtiff/tools/tiffcrop.c:8499. Incorrect updating of     buffer size after rotateImage() in tiffcrop cause heap-buffer-overflow and SEGV. (CVE-2023-25433)

  - libtiff 4.5.0 is vulnerable to Buffer Overflow in uv_encode() when libtiff reads a corrupted little-endian     TIFF file and specifies the output to be big-endian. (CVE-2023-26966)

  - 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 NULL pointer dereference in TIFFClose() is caused by a failure to open an output file (non-existent path     or a path that requires permissions like /dev/null) while specifying zones. (CVE-2023-3316)

  - A memory leak flaw was found in Libtiff's tiffcrop utility. This issue occurs when tiffcrop operates on a     TIFF image file, allowing an attacker to pass a crafted TIFF image file to tiffcrop utility, which causes     this memory leak issue, resulting an application crash, eventually leading to a denial of service.
    (CVE-2023-3576)

  - A flaw was found in libtiff. A specially crafted tiff file can lead to a segmentation fault due to a     buffer overflow in the Fax3Encode function in libtiff/tif_fax3.c, resulting in a denial of service.
    (CVE-2023-3618)

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

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2023:4371-1 advisory.

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

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 ALAS2-2023-2300 advisory.

  - There exists one heap buffer overflow in _TIFFmemcpy in tif_unix.c in libtiff 4.0.10, which allows an     attacker to cause a denial-of-service through a crafted tiff file. (CVE-2020-18768)

  - A heap buffer overflow in ExtractImageSection function in tiffcrop.c in libtiff library Version 4.3.0     allows attacker to trigger unsafe or out of bounds memory access via crafted TIFF image file which could     result into application crash, potential information disclosure or any other context-dependent impact     (CVE-2022-0891)

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