Description Laura Pardo 2018-05-16 22:00:15 UTC
A flaw was found in LibTIFF through 4.0.9. TIFFWriteDirectorySec() function in tif_dirwrite.c allows remote attackers to cause a denial of service (assertion failure and application crash) via a crafted file.

This issue did not affect the versions of libtiff as shipped with Red Hat Enterprise Linux 5 and 6 as they did not include the vulnerable code.
