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 Description =========== 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.
