Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) UNIX symbolic link following (CVE-ID: CVE-2020-15861)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a symlink following issue in snmpd. A local user can bypass implemented security mechanism via *snmp-mibs-downloader package* and execute arbitrary commands on the system as root.
2) Incorrect permission assignment for critical resource (CVE-ID: CVE-2020-15862)
The vulnerability allows a remote user to escalate privileges on the system.
The vulnerability exists due to insecure permissions set by the Net-snmp installed on Debian-based systems. A remote user can overwrite files in net-snmp directory via EXTEND MIB and execute arbitrary code on the system with root privileges.
3) Out-of-bounds write (CVE-ID: CVE-2022-24805)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when handling INDEX of NET-SNMP-VACM-MIB. A remote attacker can trick the victim into loading a specially crafted MIB collection, trigger an out-of-bounds write and execute arbitrary code on the target system.
4) Input validation error (CVE-ID: CVE-2022-24806)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when SETing malformed OIDs in master agent and subagent simultaneously. A remote user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
5) Out-of-bounds write (CVE-ID: CVE-2022-24807)
The vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a boundary error in a SET request to SNMP-VIEW-BASED-ACM-MIB::vacmAccessTable. A remote user can pass a malformed OID in a SET request, trigger an out-of-bounds write and execute arbitrary code on the target system.
6) NULL pointer dereference (CVE-ID: CVE-2022-24808)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in NET-SNMP-AGENT-MIB::nsLogTable when handling malformed OID in a SET request. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack.
7) NULL pointer dereference (CVE-ID: CVE-2022-24809)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in nsVacmAccessTable when handling malformed OID in GET-NEXT. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack.
8) NULL pointer dereference (CVE-ID: CVE-2022-24810)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in nsVacmAccessTable when handling malformed OID in a SET request. A remote user can pass specially crafted data to the application and perform a denial of service (DoS) attack.
9) NULL pointer dereference (CVE-ID: CVE-2022-44792)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the handle_ipDefaultTTL() function in agent/mibgroup/ip-mib/ip_scalars.c. A remote non-authenticated attacker can send specially crafted UDP to the application and perform a denial of service (DoS) attack.
10) NULL pointer dereference (CVE-ID: CVE-2022-44793)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the handle_ipv6IpForwarding() function in agent/mibgroup/ip-mib/ip_scalars.c. A remote attacker can send specially crafted UDP packets to the application and perform a denial of service (DoS) attack.
