New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

The LZWEncode function in tif_lzw.c in the bmp2tiff tool in LibTIFF 4.0.6 and earlier, when the "-c lzw" option is used, allows remote attackers to cause a denial of service (buffer over-read) via a crafted BMP image.
