"This update fixes two security issues :

  - 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-2010-0427 :
    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). (CVE-2010-0426 : CVSS v2 Base Score: 6.6)"
