|Gentoo Linux Security Advisory
Title: rssh: Privilege escalation (GLSA 200512-15)
Date: December 27, 2005
Local users could gain root privileges by chrooting into arbitrary directories.
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.
Vulnerable: < 2.3.0
Unaffected: >= 2.3.0
Architectures: All supported architectures
Max Vozeler discovered that the rssh_chroot_helper command allows local users to chroot into arbitrary directories.
A local attacker could exploit this vulnerability to gain root privileges by chrooting into arbitrary directories.
There is no known workaround at this time.
All rssh users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-shells/rssh-2.3.0"
