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.
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.
