Debian Security Advisory DSA-4543-1 security@debian.org
https://www.debian.org/security/ Salvatore Bonaccorso
October 14, 2019 https://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : sudo
CVE ID : CVE-2019-14287
Debian Bug : 942322
Joe Vennix discovered that sudo, a program designed to provide limited
super user privileges to specific users, when configured to allow a user
to run commands as an arbitrary user via the ALL keyword in a Runas
specification, allows to run commands as root by specifying the user ID
- - -1 or 4294967295. This could allow a user with sufficient sudo
privileges to run commands as root even if the Runas specification
explicitly disallows root access.
Details can be found in the upstream advisory at
https://www.sudo.ws/alerts/minus_1_uid.html .
For the oldstable distribution (stretch), this problem has been fixed
in version 1.8.19p1-2.1+deb9u1.
For the stable distribution (buster), this problem has been fixed in
version 1.8.27-1+deb10u1.
We recommend that you upgrade your sudo packages.

tracker page at:
