GLSA-200506-22 : sudo: Arbitrary command execution
Medium Nessus Plugin ID 18549
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200506-22 (sudo: Arbitrary command execution)
The sudoers file is used to define the actions sudo users are permitted to perform. Charles Morris discovered that a specific layout of the sudoers file could cause the results of an internal check to be clobbered, leaving sudo vulnerable to a race condition.
Successful exploitation would permit a local sudo user to execute arbitrary commands as another user.
Reorder the sudoers file using the visudo utility to ensure the 'ALL' pseudo-command precedes other command definitions.
SolutionAll sudo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-admin/sudo-1.6.8_p9'
