Synopsis ========
Local users could gain root privileges by chrooting into arbitrary directories.
Background ==========
rssh is a restricted shell, allowing only a few commands like scp or sftp. It is often used as a complement to OpenSSH to provide limited access to users.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-shells/rssh < 2.3.0 >= 2.3.0
Description ===========
Max Vozeler discovered that the rssh_chroot_helper command allows local users to chroot into arbitrary directories.
Impact ======
A local attacker could exploit this vulnerability to gain root privileges by chrooting into arbitrary directories.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All rssh users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-shells/rssh-2.3.0"
