Synopsis
========
A vulnerability has been discovered in sudo which could result in denial
of service.
Background
==========
sudo allows a system administrator to give users the ability to run
commands as other users.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-admin/sudo < 1.9.12-r1 >= 1.9.12-r1
Description
===========
In certain password input handling, sudo incorrectly assumes the
password input is at least nine bytes in size, leading to a heap buffer
overread.
Impact
======
In the worst case, the heap buffer overread can result in the denial of
service of the sudo process.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All sudo users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/sudo-1.9.12-r1"
