CVE-2009-4128

Publication date 1 December 2009

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

GNU GRand Unified Bootloader (GRUB) 2 1.97 only compares the submitted portion of a password with the actual password, which makes it easier for physically proximate attackers to conduct brute force attacks and bypass authentication by submitting a password whose length is 1.
