"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0094 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

      CVE-2022-3627:
      An out-of-bounds write flaw was found in the _TIFFmemcpy function in libtiff/tif_unix.c in the libtiff
    package. By persuading a victim to open a specially-crafted TIFF image file, a remote attacker could cause
    a denial of service condition.
      CVE-2022-3970:
      An integer overflow flaw was found in LibTIFF. This issue exists in the TIFFReadRGBATileExt function of
    the libtiff/tif_getimage.c file, and may lead to a buffer overflow.
      CVE-2022-2519:
      A double-free flaw was found in the tiffcrop tool distributed with the libtiff tools package. The
    double-free issue leads to a denial of service, impacting the availability.
      CVE-2022-2520:
      A flaw was found in libtiff 4.4.0rc1. There is a sysmalloc assertion fail in rotateImage() at
    tiffcrop.c:8621 that can cause program crash when reading a crafted input.
      CVE-2022-2521:
      It was found in libtiff 4.4.0rc1 that there is an invalid pointer free operation in TIFFClose() at
    tif_close.c:131 called by tiffcrop.c:2522 that can cause a program crash and denial of service while
    processing crafted input.
      CVE-2022-2953:
      An out-of-bound read flaw was found in LibTIFF, in extractImageSection in the tools/tiffcrop.c:6905,
    allowing attackers to cause a denial of service via a crafted tiff file.
      CVE-2022-2057:
      A divide-by-zero vulnerability was found in libtiff. This flaw allows an attacker to cause a denial of
    service via a crafted tiff file.
      CVE-2022-2058:
      A divide-by-zero vulnerability was found in libtiff. This flaw allows an attacker to cause a denial of
    service via a crafted tiff file.
