Subject: [BUG] Out of bound read of size 1 in __d_alloc function which further leads to __default_memcpy function
Date: Sun, 18 Apr 2021 01:10:10 +0530	[thread overview]
Message-ID: <CANi4_RU6QrU-ciUTpkLzGxp4fbibn0Dhyo4xP1m0=Mxm5LA74g@mail.gmail.com> (raw)

Hi,

I have found the Out of bound read issue of size 1 when argv[2] is "" in
__d_alloc function fs/fs.c:1254 which further goes
and crashes into  __default_memcpy call lib/string.c:562

Tested on:
- barebox-2021.04.0
- git commit af0f068a6edad45b033e772056ac0352e1ba3613

Host information:
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.04
DISTRIB_CODENAME=focal
DISTRIB_DESCRIPTION="Ubuntu 20.04.2 LTS"

Reproduce:
type the command below in the barebox shell:
nfs somefile ""
then crash observed.

Crash log (ASAN):
barebox@Sandbox:/ nfs file ""
