USN28-1 : sudo vulnerability |

sudo vulnerability Detailed Explanation for this Vulnerability Assessment Summary : The remote package "sudo" is missing a security patch. Description : Liam Helmer discovered an input validation flaw in sudo. When the standard shell "bash" starts up, it searches the environment for variables with a value beginning with "()". For each of these variables a function with the same name is created, with the function body filled in from the environment variable's value. A malicious user with sudo access to a shell script that uses bash can use this feature to substitute arbitrary commands for any non-fully-qualified programs called from the script. Therefore this flaw can lead to privilege escalation. Solution : Upgrade to : - sudo-1.6.7p5-1ubuntu4.1 (Ubuntu 4.10) Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
