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 grub_ext2_read_block function in fs/ext2.c in GNU GRUB before 2013-11-12, as used in shlr/grub/fs/ext2.c in radare2 1.5.0, allows remote attackers to cause a denial of service (excessive stack use and application crash) via a crafted binary file, related to use of a variable-size stack array.
