Crash when reading directory #146

Closed tspivey closed 1 year ago

tspivey commented 4 years ago

Steps to reproduce:

dd if=/dev/zero of=exfat.img bs=1024k count=10
mkfs.exfat exfat.img
mount exfat.img /mnt
touch /mnt/$'\355''a '
ls /mnt

After running that, I get: ls: reading directory '/mnt': Software caused connection abort

Thanks for the detailed bug report!

The root cause is the utf8_to_wchar() function: is does not check the upper 2 bits of the 2nd and subsequent bytes in the UTF-8 sequence.
