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.

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.

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.

  - 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)
