LXD vulnerable to Race Condition
Quick fix
GHSA-8mpq-fmr3-6jxv — github.com/lxc/lxd: upgrade to the fixed version with the command below.
go get github.com/lxc/lxd@v0.0.0-20151004155856-19c6961cc101Details
LXD before version 0.19-0ubuntu5 `doUidshiftIntoContainer()` has an unsafe `Chmod()` call that races against the stat in the `Filepath.Walk()` function. A symbolic link created in that window could cause any file on the system to have any mode of the attacker's choice.
