The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

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.

An update of the libtiff package has been released.

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 ALAS2-2022-1780 advisory.

    Integer overflow in the writeBufferToSeparateStrips function in tiffcrop.c in LibTIFF before 4.0.7 allows     remote attackers to cause a denial of service (out-of-bounds read) via a crafted tif file. (CVE-2016-9532)

    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)

    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 where a NULL source pointer passed as an argument to the memcpy() function     within the TIFFFetchStripThing() in tif_dirread.c. This flaw allows an attacker with a crafted TIFF file     to exploit this flaw, causing a crash and leading to a denial of service. (CVE-2022-0561)

    A reachable assertion failure was found in libtiff's JBIG functionality. This flaw allows an attacker who     can submit a crafted file to an application linked with libtiff and using the JBIG functionality, causes a     crash via an assertion failure, leading to a denial of service. The exact mechanism and conditions around     this issue are dependent on how the application uses libtiff. (CVE-2022-0865)

    A NULL pointer dereference flaw was found in Libtiff. This flaw allows an attacker with a crafted TIFF     file to cause a crash that leads to a denial of service. (CVE-2022-0907)

    A flaw was found in LibTIFF where a NULL source pointer passed as an argument to the memcpy() function     within the TIFFFetchNormalTag() in tif_dirread.c. This flaw allows an attacker with a crafted TIFF file to     cause a crash that leads to a denial of service. (CVE-2022-0908)

    A floating-point exception (FPE) flaw was found in LibTIFF's computeOutputPixelOffsets() function in     tiffcrop.c file. This flaw allows an attacker with a crafted TIFF file to trigger a divide-by-zero error,     causing a crash that leads to a denial of service. (CVE-2022-0909)

    A heap buffer overflow flaw was found in Libtiffs' cpContigBufToSeparateBuf() function of the tiffcp.c     file. This flaw allows an attacker with a crafted TIFF file to trigger a heap out-of-bounds read access     issue, causing a crash that leads to a denial of service. (CVE-2022-0924)

    A buffer overflow vulnerability was found in libtiff. This flaw allows an attacker with network access to     pass specially crafted files, causing an application to halt or crash. The root cause of this issue was     from the memcpy function in tif_unix.c. (CVE-2022-22844)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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