Summary:	The remote host is missing an update for the Debian 'sudo' package(s) announced via the DLA-3181-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'sudo' package(s) announced via the DLA-3181-1 advisory. Vulnerability Insight: 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. CVE-2021-23239 The sudoedit personality of Sudo before 1.9.5 may allow a local unprivileged user to perform arbitrary directory-existence tests by winning a sudo_edit.c race condition in replacing a user-controlled directory by a symlink to an arbitrary path. For Debian 10 Buster, this problem has been fixed in version 1.8.27-1+deb10u4. We recommend that you upgrade your sudo packages.
