CVE-2010-0426 sudo: sudoedit option can possibly allow for arbitrary code execution
CVE-2010-0427 sudo: Fails to reset group permissions if runas_default set
A privilege escalation flaw was found in the way sudo handled the sudoedit pseudo-command. If a local user were authorized by the sudoers file to use this pseudo-command, they could possibly leverage this flaw to execute arbitrary code with the privileges of the root user. (CVE-2010-0426)
The sudo utility did not properly initialize supplementary groups when the βrunas_defaultβ option (in the sudoers file) was used. If a local user were authorized by the sudoers file to perform their sudo commands under the account specified with βrunas_defaultβ, they would receive the root userβs supplementary groups instead of those of the intended target user, giving them unintended privileges.
