[GLSA-200512-17] scponly: Multiple privilege escalation issues |
||
scponly: Multiple privilege escalation issues Detailed Explanation for this Vulnerability Assessment 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 permits 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 permit to escape the shell restrictions and execute arbitrary programs. Workaround There is no known workaround at this time. References: http://sublimation.org/scponly/index.html#relnotes Solution: All scponly users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/scponly-4.2" Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: (C) 2005 Michel Arboi |
