  - A NULL Pointer Dereference occurs in the function     TIFFPrintDirectory in tif_print.c in LibTIFF 4.0.9 when     using the tiffinfo tool to print crafted TIFF     information, a different vulnerability than     CVE-2017-18013. (This affects an earlier part of the     TIFFPrintDirectory function that was not addressed by     the CVE-2017-18013 patch.)(CVE-2018-7456)

  - _TIFFCheckMalloc and _TIFFCheckRealloc in tif_aux.c in     LibTIFF through 4.0.10 mishandle Integer Overflow     checks because they rely on compiler behavior that is     undefined by the applicable C standards. This can, for     example, lead to an application crash.(CVE-2019-14973)

  - tif_getimage.c in LibTIFF through 4.0.10, as used in     GDAL through 3.0.1 and other products, has an integer     overflow that potentially causes a heap-based buffer     overflow via a crafted RGBA image, related to a     'Negative-size-param' condition.(CVE-2019-17546)

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 installation on the remote host is affected by the following vulnerabilities :

  - The libtiff package contains a library of functions for     manipulating TIFF (Tagged Image File Format) image     format files. TIFF is a widely used file format for     bitmapped images. TIFF files usually end in the .tif     extension and they are often quite large. The libtiff     package should be installed if you need to manipulate     TIFF format image files. Security Fix(es):There is a     reachable assertion abort in the function     TIFFWriteDirectoryTagSubifd() in LibTIFF 4.0.8, related     to tif_dirwrite.c and a SubIFD tag. A crafted input     will lead to a remote denial of service     attack.(CVE-2017-13727)The putagreytile function in     tif_getimage.c in LibTIFF 4.0.7 has a left-shift     undefined behavior issue, which might allow remote     attackers to cause a denial of service (application     crash) or possibly have unspecified other impact via a     crafted image.(CVE-2017-7592)An issue was discovered in     LibTIFF 4.0.9.
