Package : net-snmp Version : 5.7.3+dfsg-1.7+deb9u2 Debian Bug : #965166
A privilege escalation vulnerability vulnerability was discovered in Net-SNMP, a set of tools for collecting and organising information about devices on computer networks.
Upstream notes that:
It is still possible to enable this MIB via the --with-mib-modules configure option.
Another MIB that provides similar functionality, namely ucd-snmp/extensible, is disabled by default.
The security risk of ucd-snmp/pass and ucd-snmp/pass_persist is lower since these modules only introduce a security risk if the invoked scripts are exploitable.
For Debian 9 "Stretch", this issue has been fixed in net-snmp version 5.7.3+dfsg-1.7+deb9u2.
We recommend that you upgrade your net-snmp packages.
