 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3181-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb November 07, 2022 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 Package : sudo Version : 1.8.27-1+deb10u4 CVE ID : CVE-2021-23239

 It was discovered that there was a information disclosure utility in sudo, a tool used to provide limited superuser privileges to specific users.

 A local unprivileged user may have been able to perform arbitrary directory-existence tests by exploiting a race condition in sudoedit.

 For Debian 10 buster, this problem has been fixed in version 1.8.27-1+deb10u4.

 We recommend that you upgrade your sudo packages.

 For the detailed security status of sudo please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/sudo

 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the sudo packages.
