[GLSA-200512-17] scponly: Multiple privilege escalation issues Vulnerability Scan
Vulnerability Scan Summary
scponly: Multiple privilege escalation issues
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200512-17
(scponly: Multiple privilege escalation issues)
Max Vozeler discovered that the scponlyc command allows users to
chroot into arbitrary directories. Furthermore, Pekka Pessi reported
that scponly insufficiently validates command-line parameters to a scp
or rsync command.
Impact
A local attacker could gain root rights by chrooting into
arbitrary directories containing hardlinks to setuid programs. A remote
scponly user could also send malicious parameters to a scp or rsync
command that would allow to escape the shell restrictions and execute
arbitrary programs.
Workaround
There is no known workaround at this time.

Solution:
All scponly users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/scponly-4.2"
Threat Level: High
