Log message:
net-snmp py-netsnmp: updated to 5.9.3

*5.9.3*:
    security:
      - These two CVEs can be exploited by a user with read-only credentials:
          - CVE-2022-24805 A buffer overflow in the handling of the INDEX of
            NET-SNMP-VACM-MIB can cause an out-of-bounds memory access.
          - CVE-2022-24809 A malformed OID in a GET-NEXT to the nsVacmAccessTable
            can cause a NULL pointer dereference.
      - These CVEs can be exploited by a user with read-write credentials:
          - CVE-2022-24806 Improper Input Validation when SETing malformed
            OIDs in master agent and subagent simultaneously
          - CVE-2022-24807 A malformed OID in a SET request to
            SNMP-VIEW-BASED-ACM-MIB::vacmAccessTable can cause an
            out-of-bounds memory access.
          - CVE-2022-24808 A malformed OID in a SET request to
            NET-SNMP-AGENT-MIB::nsLogTable can cause a NULL pointer dereference
          - CVE-2022-24810 A malformed OID in a SET to the nsVacmAccessTable
            can cause a NULL pointer dereference.
      - To avoid these flaws, use strong SNMPv3 credentials and do not share them.
        If you must use SNMPv1 or SNMPv2c, use a complex community string
        and enhance the protection by restricting access to a given IP address range.
      - Thanks are due to Yu Zhang of VARAS@IIE and Nanyu Zhong of VARAS@IIE for
        reporting the following CVEs that have been fixed in this release, and
        to Arista Networks for providing fixes.

    misc:
      - Snmp-create-v3-user: Fix the snmpd.conf path   @datadir@ is
        expanded in ${datarootdir} so datarootdir must be set before
        @datadir@ is used.

    general: Many bug fixes
