Test ID:1.3.6.1.4.1.25623.1.0.704614
Category:Debian Local Security Checks
Title:Debian: Security Advisory for sudo (DSA-4614-1)
Summary:The remote host is missing an update for the 'sudo'; package(s) announced via the DSA-4614-1 advisory.
Description:Summary:
The remote host is missing an update for the 'sudo'
package(s) announced via the DSA-4614-1 advisory.

Vulnerability Insight:
Joe Vennix discovered a stack-based buffer overflow vulnerability in
sudo, a program designed to provide limited super user privileges to
specific users, triggerable when configured with the pwfeedback
option enabled. An unprivileged user can take advantage of this flaw to obtain
full root privileges.

Details can be found in the referenced upstream advisory.

Affected Software/OS:
'sudo' package(s) on Debian Linux.

Solution:
For the oldstable distribution (stretch), this problem has been fixed
in version 1.8.19p1-2.1+deb9u2.

For the stable distribution (buster), exploitation of the bug is
prevented due to a change in EOF handling introduced in 1.8.26.

We recommend that you upgrade your sudo packages.

CVSS Score:
