CWE-789
Memory Allocation with Excessive Size Value
The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated.
CVE-2022-22188 (GCVE-0-2022-22188)

Title
Junos OS: QFX5100/QFX5110/QFX5120/QFX5200/QFX5210/EX4600/EX4650 Series: When storm control profiling is enabled and a device is under an active storm, a Heap-based Buffer Overflow in the PFE will cause a device to hang.
Summary
An Uncontrolled Memory Allocation vulnerability leading to a Heap-based Buffer Overflow in the packet forwarding engine (PFE) of Juniper Networks Junos OS allows a network-based unauthenticated attacker to flood the device with traffic leading to a Denial of Service (DoS). The device must be configured with storm control profiling limiting the number of unknown broadcast, multicast, or unicast traffic to be vulnerable to this issue. This issue affects: Juniper Networks Junos OS on QFX5100/QFX5110/QFX5120/QFX5200/QFX5210/EX4600/EX4650 Series; 20.2 version 20.2R1 and later versions prior to 20.2R2. This issue does not affect: Juniper Networks Junos OS versions prior to 20.2R1.

Title
Junos OS: EX4300-MP, EX4600, QFX5000 Series: In VxLAN scenarios specific packets processed cause a memory leak leading to a PFE crash
Summary
In VxLAN scenarios on EX4300-MP, EX4600, QFX5000 Series devices an Uncontrolled Memory Allocation vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS allows an unauthenticated adjacently located attacker sending specific packets to cause a Denial of Service (DoS) condition by crashing one or more PFE's when they are received and processed by the device. Upon automatic restart of the PFE, continued processing of these packets will cause the memory leak to reappear. Depending on the volume of packets received the attacker may be able to create a sustained Denial of Service (DoS) condition. This issue affects: Juniper Networks Junos OS on EX4300-MP, EX4600, QFX5000 Series: 17.1 version 17.1R1 and later 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 18.4R1-S8, 18.4R2-S6, 18.4R3-S6; 19.1 versions prior to 19.1R3-S4; 19.2 versions prior to 19.2R1-S7, 19.2R3-S1; 19.3 versions prior to 19.3R2-S6, 19.3R3-S1; 19.4 versions prior to 19.4R1-S4, 19.4R2-S4, 19.4R3-S1; 20.1 versions prior to 20.1R2; 20.2 versions prior to 20.2R2-S3, 20.2R3; 20.3 versions prior to 20.3R2. This issue does not affect Junos OS versions prior to 17.1R1.

CVE-2022-34917 (GCVE-0-2022-34917)
Vulnerability from cvelistv5 – Published: 2022-09-20 08:35 – Updated: 2025-05-29 13:39

Title
Unauthenticated clients may cause OutOfMemoryError on Apache Kafka Brokers
Summary
A security vulnerability has been identified in Apache Kafka. It affects all releases since 2.8.0. The vulnerability allows malicious unauthenticated clients to allocate large amounts of memory on brokers. This can lead to brokers hitting OutOfMemoryException and causing denial of service. Example scenarios: - Kafka cluster without authentication: Any clients able to establish a network connection to a broker can trigger the issue. - Kafka cluster with SASL authentication: Any clients able to establish a network connection to a broker, without the need for valid SASL credentials, can trigger the issue. - Kafka cluster with TLS authentication: Only clients able to successfully authenticate via TLS can trigger the issue. We advise the users to upgrade the Kafka installations to one of the 3.2.3, 3.1.2, 3.0.2, 2.8.2 versions.

CVE-2022-36078 (GCVE-0-2022-36078)
Vulnerability from cvelistv5 – Published: 2022-09-02 12:15 – Updated: 2025-04-22 17:40
VLAI
Title
Slice Memory Allocation with Excessive Size Value in binary
Summary
Binary provides encoding/decoding in Borsh and other formats. The vulnerability is a memory allocation vulnerability that can be exploited to allocate slices in memory with (arbitrary) excessive size value, which can either exhaust available memory or crash the whole program. When using `github.com/gagliardetto/binary` to parse unchecked (or wrong type of) data from untrusted sources of input (e.g. the blockchain) into slices, it's possible to allocate memory with excessive size. When `dec.Decode(&val)` method is used to parse data into a structure that is or contains slices of values, the length of the slice was previously read directly from the data itself without any checks on the size of it, and then a slice was allocated. This could lead to an overflow and an allocation of memory with excessive size value. Users should upgrade to `v0.7.1` or higher. A workaround is not to rely on the `dec.Decode(&val)` function to parse the data, but to use a custom `UnmarshalWithDecoder()` method that reads and checks the length of any slice.

CVE-2023-20089 (GCVE-0-2023-20089)
Vulnerability from cvelistv5 – Published: 2023-02-23 00:00 – Updated: 2024-10-25 16:03

Title
Cisco Nexus 9000 Series Fabric Switches in ACI Mode Link Layer Discovery Protocol Memory Leak Denial of Service Vulnerability
Summary
A vulnerability in the Link Layer Discovery Protocol (LLDP) feature for Cisco Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) Mode could allow an unauthenticated, adjacent attacker to cause a memory leak, which could result in an unexpected reload of the device. This vulnerability is due to incorrect error checking when parsing ingress LLDP packets. An attacker could exploit this vulnerability by sending a steady stream of crafted LLDP packets to an affected device. A successful exploit could allow the attacker to cause a memory leak, which could result in a denial of service (DoS) condition when the device unexpectedly reloads. Note: This vulnerability cannot be exploited by transit traffic through the device. The crafted LLDP packet must be targeted to a directly connected interface, and the attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent). In addition, the attack surface for this vulnerability can be reduced by disabling LLDP on interfaces where it is not required.

CVE-2023-20108 (GCVE-0-2023-20108)
Vulnerability from cvelistv5 – Published: 2023-06-28 00:00 – Updated: 2024-08-02 08:57

Summary
A vulnerability in the XCP Authentication Service of the Cisco Unified Communications Manager IM & Presence Service (Unified CM IM&P) could allow an unauthenticated, remote attacker to cause a temporary service outage for all Cisco Unified CM IM&P users who are attempting to authenticate to the service, resulting in a denial of service (DoS) condition.
This vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted login message to the affected device. A successful exploit could allow the attacker to cause an unexpected restart of the authentication service, preventing new users from successfully authenticating. Exploitation of this vulnerability does not impact Cisco Unified CM IM&P users who were authenticated prior to an attack.

Mitigation
Phases: Implementation, Architecture and Design
Description:
- Perform adequate input validation against any value that influences the amount of memory that is allocated. Define an appropriate strategy for handling requests that exceed the limit, and consider supporting a configuration option so that the administrator can extend the amount of memory to be used if necessary.
Mitigation
Phase: Operation
Description:
- Run your program using system-provided resource limits for memory. This might still cause the program to crash or exit, but the impact to the rest of the system will be minimized.
No CAPEC attack patterns related to this CWE.
