Title
Ovn: ovn: heap over-read in icmp error response generation
Summary
When generating an ICMP Destination Unreachable or Packet Too Big response, the handler copies a portion of the original packet into the ICMP error body using the IP header's self-declared total length (ip_tot_len for IPv4, ip6_plen for IPv6) without validating it against the actual packet buffer size. A VM can send a short packet with an inflated IP length field that triggers an ICMP error (e.g., by hitting a reject ACL), causing ovn-controller to read heap memory beyond the valid packet data and include it in the ICMP response sent back to the VM.

CVE-2026-3868 (GCVE-0-2026-3868)
Vulnerability from cvelistv5 – Published: 2026-04-27 02:56 – Updated: 2026-04-27 15:14

Summary
An improper handling of the length parameter inconsistency vulnerability has been identified in Moxa’s Secure Router. Because of improper validation of length parameters in the HTTPS management interface, an unauthenticated remote attacker could send specially crafted requests that trigger a buffer overflow condition, causing the web service to become unresponsive. Successful exploitation may result in a denial-of-service condition requiring a device reboot to restore normal operation. While successful exploitation can severely impact the availability of the affected device, no impact to the confidentiality or integrity of the affected product has been identified. Additionally, no confidentiality, integrity, or availability impact to the subsequent system has been identified.

Title
Junos OS and Junos OS Evolved: In an EVPN environment, receipt of specifically malformed BGP update causes RPD crash
Summary
An Improper Handling of Length Parameter Inconsistency vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a logically adjacent BGP peer sending a specifically malformed BGP packet to cause rpd to crash and restart, resulting in a Denial of Service (DoS). Continued receipt and processing of this packet will create a sustained Denial of Service (DoS) condition.
Only systems configured for Ethernet Virtual Private Networking (EVPN) signaling are vulnerable to this issue.
This issue affects iBGP and eBGP, and both IPv4 and IPv6 are affected by this vulnerability.This issue affects:
Junos OS:
* all versions before 21.4R3-S11,
* from 22.2 before 22.2R3-S7,
* from 22.4 before 22.4R3-S7,
* from 23.2 before 23.2R2-S4,
* from 23.4 before 23.4R2-S5,
* from 24.2 before 24.2R2-S1,
* from 24.4 before 24.4R1-S3, 24.4R2;
Junos OS Evolved:
* all versions before 22.2R3-S7-EVO,
* from 22.4-EVO before 22.4R3-S7-EVO,
* from 23.2-EVO before 23.2R2-S4-EVO,
* from 23.4-EVO before 23.4R2-S5-EVO,
* from 24.2-EVO before 24.2R2-S1-EVO,
* from 24.4-EVO before 24.4R1-S3-EVO, 24.4R2-EVO.

Summary
In ConnMan through 1.44, parse_rr in dnsproxy.c has a memcpy length that depends on an RR RDLENGTH value, i.e., *rdlen=ntohs(rr->rdlen) and memcpy(response+offset,*end,*rdlen) without a check for whether the sum of *end and *rdlen exceeds max. Consequently, *rdlen may be larger than the amount of remaining packet data in the current state of parsing. Values of stack memory locations may be sent over the network in a response.

Title
Junos OS: SRX Series: A device configured for vector routing crashes when receiving malformed traffic
Summary
An Improper Handling of Length Parameter Inconsistency vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).
When a device configured for Secure Vector Routing (SVR) receives a specifically malformed packet the PFE will crash and restart.
This issue affects Junos OS on SRX Series:
* All 21.4 versions,
* 22.2 versions before 22.2R3-S6,
* 22.4 versions before 22.4R3-S6,
* 23.2 versions before 23.2R2-S3,
* 23.4 versions before 23.4R2-S4,
* 24.2 versions before 24.2R2.
This issue does not affect versions before 21.4.

CVE-2025-29931 (GCVE-0-2025-29931)
Vulnerability from cvelistv5 – Published: 2025-04-17 11:05 – Updated: 2025-04-17 14:43

VEX
Summary
A vulnerability has been identified in TeleControl Server Basic (All versions < V3.1.2.2). The affected product does not properly validate a length field in a serialized message which it uses to determine the amount of memory to be allocated for deserialization. This could allow an unauthenticated remote attacker to cause the application to allocate exhaustive amounts of memory and subsequently create a partial denial of service condition.
Successful exploitation is only possible in redundant Telecontrol Server Basic setups and only if the connection between the redundant servers has been disrupted.

Title
NamelessMC Has Lack of Length Validation for s Parameter in GET Requests
Summary
NamelessMC is a free, easy to use & powerful website software for Minecraft servers. In version 2.1.4 and prior, the s parameter in GET requests for forum search functionality lacks length validation, allowing attackers to submit excessively long search queries. This oversight can lead to performance degradation and potential denial-of-service (DoS) attacks. This issue has been patched in version 2.2.0.

Mitigation
Implementation
When processing structured incoming data containing a size field followed by raw data, ensure that you identify and resolve any inconsistencies between the size field and the actual size of the data.
Mitigation
Implementation
Do not let the user control the size of the buffer.
Mitigation
Implementation
Validate that the length of the user-supplied data is consistent with the buffer size.
CAPEC-47: Buffer Overflow via Parameter Expansion
In this attack, the target software is given input that the adversary knows will be modified and expanded in size during processing. This attack relies on the target software failing to anticipate that the expanded data may exceed some internal limit, thereby creating a buffer overflow.
