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

There is an infinite loop in Exiv2::Jp2Image::encodeJp2Header of jp2image.cpp in Exiv2 0.27-RC3. A crafted input will lead to a remote denial of service attack.
