Summary

In LibTIFF 4.0.8, there is a memory leak in tif_jbig.c. A crafted TIFF document can lead to a memory leak resulting in a remote denial of service attack.

Common Attack Pattern Enumeration and Classification (CAPEC)

  • HTTP DoS
    An attacker performs flooding at the HTTP level to bring down only a particular web application rather than anything listening on a TCP/IP connection. This denial of service attack requires substantially fewer packets to be sent which makes DoS harder to detect. This is an equivalent of SYN flood in HTTP. The idea is to keep the HTTP session alive indefinitely and then repeat that hundreds of times. This attack targets resource depletion weaknesses in web server software. The web server will wait to attacker's responses on the initiated HTTP sessions while the connection threads are being exhausted.

        attackers to cause a denial of service (divide-by-zero
        error and application crash) via a crafted Tiff
        image.(CVE-2016-5323)The DumpModeDecode function in
        libtiff 4.0.6 and earlier allows attackers to cause a
        denial of service (invalid read and crash) via a
        crafted tiff image.(CVE-2016-5321)The TIFFReadRawStrip1
        and TIFFReadRawTile1 functions in tif_read.c in libtiff
        before 4.0.7 allows remote attackers to cause a denial
        of service (crash) or possibly obtain sensitive
        information via a negative index in a file-content
        buffer.(CVE-2016-6223)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)The TIFFWriteDirectorySec()
        function in tif_dirwrite.c in LibTIFF through 4.0.9
        allows remote attackers to cause a denial of service
        (assertion failure and application crash) via a crafted
        file, a different vulnerability than
        CVE-2017-13726.(CVE-2018-10963)Heap-based buffer
        overflow in the cpSeparateBufToContigBuf function in
        tiffcp.c in LibTIFF 4.0.9 allows remote attackers to
        cause a denial of service (crash) or possibly have
        unspecified other impact via a crafted TIFF
        file.(CVE-2018-12900)An issue was discovered in LibTIFF
        4.0.9. There are two out-of-bounds writes in cpTags in
        tools/tiff2bw.c and tools/pal2rgb.c, which can cause a
        denial of service (application crash) or possibly have
        unspecified other impact via a crafted image
        file.(CVE-2018-17101)LibTIFF 4.0.9 (with JBIG enabled)
        decodes arbitrarily-sized JBIG into a buffer, ignoring
        the buffer size, which leads to a tif_jbig.c JBIGDecode
        out-of-bounds write.(CVE-2018-18557)In LibTIFF 4.0.9,
        there is a NULL pointer dereference in the
        TIFFWriteDirectorySec function in tif_dirwrite.c that
        will lead to a denial of service attack, as
        demonstrated by tiffset.(CVE-2018-19210)The TIFFFdOpen
        function in tif_unix.c in LibTIFF 4.0.10 has a memory
        leak, as demonstrated by pal2rgb.(CVE-2019-6128)An
        Invalid Address dereference was discovered in
        TIFFWriteDirectoryTagTransferfunction in
        libtiff/tif_dirwrite.c in LibTIFF 4.0.10, affecting the
        cpSeparateBufToContigBuf function in tiffcp.c. Remote
        attackers could leverage this vulnerability to cause a
        denial-of-service via a crafted tiff file. This is
        different from CVE-2018-12900.(CVE-2019-7663)

        possibly have unspecified other impact via a crafted
        image.(CVE-2017-7597)
    
      - tif_dirread.c in LibTIFF 4.0.7 might allow remote
        attackers to cause a denial of service (divide-by-zero
        error and application crash) via a crafted
        image.(CVE-2017-7598)
    
      - LibTIFF 4.0.7 has an 'outside the range of
        representable values of type short' undefined behavior
        issue, which might allow remote attackers to cause a
        denial of service (application crash) or possibly have
        unspecified other impact via a crafted
        image.(CVE-2017-7599)
    
      - LibTIFF 4.0.7 has an 'outside the range of
        representable values of type unsigned char' undefined
        behavior issue, which might allow remote attackers to
        cause a denial of service (application crash) or
        possibly have unspecified other impact via a crafted
        image.(CVE-2017-7600)
    
      - LibTIFF 4.0.7 has a 'shift exponent too large for
        64-bit type long' undefined behavior issue, which might

        of service via a crafted file.(CVE-2017-9403)
    
      - LibTIFF 4.0.7 allows remote attackers to cause a denial
        of service (divide-by-zero error and application crash)
        via a crafted TIFF image, related to
        libtiff/tif_ojpeg.c:816:8.(CVE-2016-10267)
    
      - tiffsplit in libtiff 4.0.6 allows remote attackers to
        cause a denial of service (out-of-bounds read) via a
        crafted file, related to changing td_nstrips in
        TIFF_STRIPCHOP mode.(CVE-2016-9273)
    
      - LibTIFF 4.0.7 has an invalid read in the _TIFFVGetField
        function in tif_dir.c, which might allow remote
        attackers to cause a denial of service (crash) via a
        crafted TIFF file.(CVE-2017-9147)
    
      - Stack-based buffer overflow in the _TIFFVGetField
        function in libtiff 4.0.6 and earlier allows remote
        attackers to crash the application via a crafted
        tiff.(CVE-2016-5318)
    
      - An issue was discovered in LibTIFF 4.0.9. There is a
        NULL pointer dereference in the function LZWDecode in
        the file tif_lzw.c.(CVE-2018-18661)
    
      - TIFFWriteScanline in tif_write.c in LibTIFF 3.8.2 has a
        heap-based buffer over-read, as demonstrated by
        bmp2tiff.(CVE-2018-10779)
    
      - The OJPEGReadHeaderInfoSecTablesDcTable function in
        tif_ojpeg.c in LibTIFF 4.0.7 allows remote attackers to
        cause a denial of service (memory leak) via a crafted
        image.(CVE-2017-7594)
    
      - LibTIFF 4.0.7 allows remote attackers to cause a denial
        of service (divide-by-zero error and application crash)
        via a crafted TIFF image, related to
        libtiff/tif_read.c:351:22.(CVE-2016-10266)
    
      - Buffer overflow in the readgifimage function in
        gif2tiff.c in the gif2tiff tool in LibTIFF 4.0.6 allows
        remote attackers to cause a denial of service
        (segmentation fault) via a crafted gif
        file.(CVE-2016-5102)
    
      - tif_read.c in LibTIFF 4.0.7 does not ensure that
        tif_rawdata is properly initialized, which might allow
        remote attackers to obtain sensitive information from
        process memory via a crafted image.(CVE-2017-7593)
    
      - A NULL Pointer Dereference occurs in the function
        TIFFPrintDirectory in tif_print.c in LibTIFF 4.0.9 when
        using the tiffinfo tool to print crafted TIFF
        information, a different vulnerability than
        CVE-2017-18013. (This affects an earlier part of the
        TIFFPrintDirectory function that was not addressed by
        the CVE-2017-18013 patch.)(CVE-2018-7456)
    
      - _TIFFCheckMalloc and _TIFFCheckRealloc in tif_aux.c in
        LibTIFF through 4.0.10 mishandle Integer Overflow
        checks because they rely on compiler behavior that is
        undefined by the applicable C standards. This can, for
        example, lead to an application crash.(CVE-2019-14973)

        libtiff/tif_read.c:523:22.(CVE-2016-10270)
    
      - The TIFFWriteDirectoryTagCheckedRational function in
        tif_dirwrite.c in LibTIFF 4.0.6 allows remote attackers
        to cause a denial of service (assertion failure and
        application exit) via a crafted TIFF
        file.(CVE-2016-10371)
    
      - The fpAcc function in tif_predict.c in the tiff2rgba
        tool in LibTIFF 4.0.6 and earlier allows remote
        attackers to cause a denial of service (divide-by-zero
        error) via a crafted TIFF image.(CVE-2016-3622)
    
      - tiffsplit in libtiff 4.0.6 allows remote attackers to
        cause a denial of service (out-of-bounds read) via a
        crafted file, related to changing td_nstrips in
        TIFF_STRIPCHOP mode.(CVE-2016-9273)
    
      - The TIFFReadDirEntryArray function in tif_read.c in
        LibTIFF 4.0.8 mishandles memory allocation for short
        files, which allows remote attackers to cause a denial
        of service (allocation failure and application crash)
        in the TIFFFetchStripThing function in tif_dirread.c
        during a tiff2pdf invocation.(CVE-2017-12944)
    
      - There is a reachable assertion abort in the function
        TIFFWriteDirectorySec() in LibTIFF 4.0.8, related to
        tif_dirwrite.c and a SubIFD tag. A crafted input will
        lead to a remote denial of service
        attack.(CVE-2017-13726)
    
      - tools/tiffcrop.c in libtiff 4.0.6 reads an undefined
        buffer in readContigStripsIntoBuffer() because of a
        uint16 integer overflow. Reported as MSVR
        35100.(CVE-2016-9538)
    
      - tools/tiffcrop.c in libtiff 4.0.6 has an out-of-bounds

        35092.(CVE-2016-9539)
    
      - In LibTIFF 4.0.8, there is a assertion abort in the
        TIFFWriteDirectoryTagCheckedLong8Array function in
        tif_dirwrite.c. A crafted input will lead to a remote
        denial of service attack.(CVE-2017-10688)
    
      - Buffer overflow in the readextension function in
        gif2tiff.c in LibTIFF 4.0.6 allows remote attackers to
        cause a denial of service (application crash) via a
        crafted GIF file.(CVE-2016-3186)
    
      - A NULL Pointer Dereference occurs in the function
        TIFFPrintDirectory in tif_print.c in LibTIFF 4.0.9 when
        using the tiffinfo tool to print crafted TIFF
        information, a different vulnerability than
        CVE-2017-18013. (This affects an earlier part of the
        TIFFPrintDirectory function that was not addressed by
        the CVE-2017-18013 patch.)(CVE-2018-7456)
    
      - In LibTIFF 4.0.9, a heap-based buffer overflow occurs
        in the function LZWDecodeCompat in tif_lzw.c via a
