grub2: CVE-2015-8370

Severity: Medium
Published: Dec 11, 2015, 12:00:00 AM UTC
Source: [NVD] · [CVE record]
EPSS: 1.09% · Oct 25, 2026

Multiple integer underflows in Grub2 1.98 through 2.02 allow physically proximate attackers to bypass authentication, obtain sensitive information, or cause a denial of service (disk corruption) via backspace characters in the (1) grub_username_get function in grub-core/normal/auth.c or the (2) grub_password_get function in lib/crypto.c, which trigger an "Off-by-two" or "Out of bounds overwrite" memory error.
