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

  • A heap-based buffer overflow flaw was found in libtiff in the handling of TIFF images in libtiff’s TIFF2PDF tool. A specially crafted TIFF file can lead to arbitrary code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.(CVE-2020-35524)

  • A flaw was found in libtiff. Due to a memory allocation failure in tif_read.c, a crafted TIFF file can lead to an abort, resulting in denial of service.(CVE-2020-35521)

  • In LibTIFF, there is a memory malloc failure in tif_pixarlog.c. A crafted TIFF document can lead to an abort, resulting in a remote denial of service attack.(CVE-2020-35522)

  • An integer overflow flaw was found in libtiff that exists in the tif_getimage.c file. This flaw allows an attacker to inject and execute arbitrary code when a user opens a crafted TIFF file. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.(CVE-2020-35523)

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.
