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

      CVE-2022-0561:
      Null source pointer passed as an argument to memcpy() function within TIFFFetchStripThing() in     tif_dirread.c in libtiff versions from 3.9.0 to 4.3.0 could lead to Denial of Service via crafted TIFF     file. For users that compile libtiff from sources, the fix is available with commit eecb0712.

      CVE-2022-0562:
      Null source pointer passed as an argument to memcpy() function within TIFFReadDirectory() in     tif_dirread.c in libtiff versions from 4.0 to 4.3.0 could lead to Denial of Service via crafted TIFF file.
    For users that compile libtiff from sources, a fix is available with commit 561599c.

The remote NewStart CGSL host, running version MAIN 6.02, has libtiff packages installed that are affected by multiple vulnerabilities:

  - Buffer overflow in the t2p_write_pdf_string function in tiff2pdf in libtiff 3.8.2 and earlier allows     attackers to cause a denial of service (crash) and possibly execute arbitrary code via a TIFF file with a     DocumentName tag that contains UTF-8 characters, which triggers the overflow when a character is sign     extended to an integer that produces more digits than expected in an sprintf call. (CVE-2006-2193)

  - Heap-based buffer overflow in the JPEG decoder in the TIFF library (libtiff) before 3.8.2 allows context-     dependent attackers to cause a denial of service and possibly execute arbitrary code via an encoded JPEG     stream that is longer than the scan line size (TiffScanLineSize). (CVE-2006-3460)

  - Heap-based buffer overflow in the PixarLog decoder in the TIFF library (libtiff) before 3.8.2 might allow     context-dependent attackers to execute arbitrary code via unknown vectors. (CVE-2006-3461)

  - Heap-based buffer overflow in the NeXT RLE decoder in the TIFF library (libtiff) before 3.8.2 might allow     context-dependent attackers to execute arbitrary code via unknown vectors involving decoding large RLE     images. (CVE-2006-3462)

  - The EstimateStripByteCounts function in TIFF library (libtiff) before 3.8.2 uses a 16-bit unsigned short     when iterating over an unsigned 32-bit value, which allows context-dependent attackers to cause a denial     of service via a large td_nstrips value, which triggers an infinite loop. (CVE-2006-3463)

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