Test ID:	1.3.6.1.4.1.25623.1.1.12.2004.28.1
Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-28-1)
Summary:	The remote host is missing an update for the 'sudo' package(s) announced via the USN-28-1 advisory.
Description:	Summary: The remote host is missing an update for the 'sudo' package(s) announced via the USN-28-1 advisory. Vulnerability Insight: 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. Affected Software/OS: 'sudo' package(s) on Ubuntu 4.10. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
