- Update from version 5.9.1 to 5.9.3
- Version 5.9.4 exists but it is indicated that SNMP over TLS and/or DTLS is not
functioning properly with various versions of OpenSSL. However I could not find which
versions mentioned in the News or Changelog. The problem will be fixed in a future
version. There are no CVE fixes in 5.9.4, only a relatively few bug fixes so I
decided to wait for the fixed version in case there are users using TLS with SNMP.
- Update of rootfile
- 6 CVE fixes in 5.9.3
- Changelog
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
5.9.2
skipped due to a last minute library versioning found bug -- use 5.9.3 instead
