Severity: Normal
Title: scponly: Multiple vulnerabilities
Date: February 12, 2008
Bugs: #201726, #203099
ID: 200802-06
Synopsis
=======
Multiple vulnerabilities in scponly allow authenticated users to bypass
security restrictions.
Background
=========
scponly is a shell for restricting user access to file transfer only
using sftp and scp.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/scponly < 4.8 >= 4.8
==========
Florian Weimer from Debian discovered that scponly does not filter the
- -o and -F options to the scp executable (CVE-2007-6415). Joachim
Breitner reported that Subversion and rsync support invokes subcommands
in an insecure manner (CVE-2007-6350).
Impact
=====
A local attacker could exploit these vulnerabilities to elevate
privileges and execute arbitrary commands on the vulnerable host.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All scponly users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/scponly-4.8"
Due to the design of scponly's Subversion support, security
restrictions can still be circumvented. Please read carefully the
SECURITY file included in the package.
