CVE-2018-19210

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.

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.

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)

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)

It was discovered that LibTIFF incorrectly handled certain malformed images. If a user or automated system were tricked into opening a specially crafted image, a remote attacker could crash the application, leading to a denial of service, or possibly execute arbitrary code with user privileges.
