Title
Junos OS and Junos OS Evolved: LLDP Out-of-Bounds Read vulnerability in l2cpd
Summary
An Out-of-bounds Read vulnerability in the processing of specially crafted LLDP frames by the Layer 2 Control Protocol Daemon (l2cpd) of Juniper Networks Junos OS and Junos OS Evolved may allow an attacker to cause a Denial of Service (DoS), or may lead to remote code execution (RCE). Continued receipt and processing of these frames, sent from the local broadcast domain, will repeatedly crash the l2cpd process and sustain the Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS: 12.3 versions prior to 12.3R12-S18; 15.1 versions prior to 15.1R7-S9; 17.3 versions prior to 17.3R3-S12; 17.4 versions prior to 17.4R2-S13, 17.4R3-S5; 18.1 versions prior to 18.1R3-S13; 18.2 versions prior to 18.2R3-S8; 18.3 versions prior to 18.3R3-S5; 18.4 versions prior to 18.4R2-S8, 18.4R3-S8; 19.1 versions prior to 19.1R3-S5; 19.2 versions prior to 19.2R3-S3; 19.3 versions prior to 19.3R2-S6, 19.3R3-S2; 19.4 versions prior to 19.4R1-S4, 19.4R2-S4, 19.4R3-S3; 20.1 versions prior to 20.1R2-S2, 20.1R3; 20.2 versions prior to 20.2R3-S1; 20.3 versions prior to 20.3R2-S1, 20.3R3; 20.4 versions prior to 20.4R2.

Configure the device to not load the L2CPD daemon using the following CLI config stanza.\n\n set system processes l2cpd-service disable\n\nAdditional protocols L2CPD daemon supports include RSTP, MSTP, VSTP, ERP, xSTP and ERP protocols. After issuing set system processes l2cpd-service disable, RSTP, MSTP, VSTP, ERP, xSTP and ERP protocols will cease to operate. Please note, this is not an exhaustive list, disabling L2CPD may affect other protocols and services that rely upon L2CPD daemon to be present. For example, L2ALD, MRVP, EVPN traffic, etc. may also cease to operate. To avoid downtime, customers considering applying this workaround should carefully test all workaround changes to their environment in a non-production environment first that mirrors or as closely as possible matches the production environment before applying to the production environment.\n\n2. Configure target interfaces on the device to disable LLDP packet processing:\n \n set protocols lldp interface \u003cinterface name\u003e disable\n\n3. On Switching platforms such as EX/QFX Series devices implement packet filters to discard LLDP packets with an EtherType of 0x88cc.\n\nFor example:\n\n set firewall family ethernet-switching filter LLDP_EXAMPLE term 1 from ether-type 0x88cc\n set firewall family ethernet-switching filter LLDP_EXAMPLE term 1 then discard\n \nWorkaround #3 does not work on MX Series devices. MX Series devices should disable LLDP processing, filter off-system, or upgrade to a fixed release.\n \n4. Lastly, as a method to reduce the risk of exploitation for this vulnerability, customers may implement off-system IDP and/or Firewall filtering methods such as disallowing LLDP EtherType to propagate completely on local segments, or by filtering broadcast addressed LLDP packets or unicast addressed LLDP packets not originated from trusted sources targeted to trusted destinations.\n\nAdditionally, it is good security practice to limit the exploitable attack surface of critical infrastructure networking equipment. Use access lists or firewall filters to limit access to the device via all means to only trusted, administrative networks, hosts and users."

VEX
Summary
An out-of-bounds (OOB) memory access flaw was found in x25_bind in net/x25/af_x25.c in the Linux kernel version v5.12-rc5. A bounds check failure allows a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Mitigation MIT-5
Implementation
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- To reduce the likelihood of introducing an out-of-bounds read, ensure that you validate and ensure correct calculations for any length argument, buffer size calculation, or offset. Be especially careful of relying on a sentinel (i.e. special character such as NUL) in untrusted inputs.
Mitigation
Architecture and Design
Strategy: Language Selection
Use a language that provides appropriate memory abstractions.
CAPEC-540: Overread Buffers
An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
