[GLSA-200409-15] Webmin, Usermin: Multiple vulnerabilities in Usermin |
||
Webmin, Usermin: Multiple vulnerabilities in Usermin Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200409-15 (Webmin, Usermin: Multiple vulnerabilities in Usermin) There is an input validation bug in the webmail feature of Usermin. Additionally, the Webmin and Usermin installation scripts write to /tmp/.webmin without properly checking if it exists first. Impact The first vulnerability permits a remote attacker to inject arbitrary shell code in a specially-crafted e-mail. This could lead to remote code execution with the rights of the user running Webmin or Usermin. The second could permit local users who know Webmin or Usermin is going to be installed to have arbitrary files be overwritten by creating a symlink by the name /tmp/.webmin that points to some target file, e.g. /etc/passwd. Workaround There is no known workaround at this time. References: http://secunia.com/advisories/12488/ http://www.webmin.com/uchanges.html Solution: All Usermin users should upgrade to the latest version: # emerge sync # emerge -pv ">=app-admin/usermin-1.090" # emerge ">=app-admin/usermin-1.090" All Webmin users should upgrade to the latest version: # emerge sync # emerge -pv ">=app-admin/webmin-1.160" # emerge ">=app-admin/webmin-1.160" Network Security Threat Level: Medium Networks Security ID: Vulnerability Assessment Copyright: (C) 2005 Michel Arboi |
