Package updates are available for Alibaba Cloud Linux 2.1903 that fix the following vulnerabilities: CVE-2016-3186: 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-2018-10779: TIFFWriteScanline in tif_write.c in LibTIFF 3.8.2 has a heap-based buffer over-read, as demonstrated by bmp2tiff. CVE-2018-10963: 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-2018-12900: 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-2018-17100: An issue was discovered in LibTIFF 4.0.9. There is a int32 overflow in multiply_ms in tools/ppm2tiff.c, which can cause a denial of service (crash) or possibly have unspecified other impact via a crafted image file. CVE-2018-17101: 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-2018-18557: 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-2018-18661: 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-2018-7456: 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-2018-8905: In LibTIFF 4.0.9, a heap-based buffer overflow occurs in the function LZWDecodeCompat in tif_lzw.c via a crafted TIFF file, as demonstrated by tiff2ps.
