  - CVE-2010-0427:CVSS v2 Base Score: 6.6 Sudo failed to
    properly reset group permissions, when 'runas_default'
    option was used. If a local, unprivileged user was
    authorized by sudoers file to perform their sudo
    commands under default user account, it could lead to
    privilege escalation CVE-2010-0426:CVSS v2 Base Score:
    6.6 A privilege escalation flaw was found in the way
    sudo used to check file paths for pseudocommands. If
    local, unprivileged user was authorized by sudoers file
    to edit one or more files, it could lead to execution of
    arbitrary code, with the privileges of privileged system
    user (root)."
