CWE-130
Improper Handling of Length Parameter Inconsistency
The product parses a formatted message or structure, but it does not handle or incorrectly handles a length field that is inconsistent with the actual length of the associated data.

Title
Rack: Content-Length mismatch in Rack::Files error responses
Summary
Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Files#fail sets the Content-Length response header using String#size instead of String#bytesize. When the response body contains multibyte UTF-8 characters, the declared Content-Length is smaller than the number of bytes actually sent on the wire. Because Rack::Files reflects the requested path in 404 responses, an attacker can trigger this mismatch by requesting a non-existent path containing percent-encoded UTF-8 characters. This results in incorrect HTTP response framing and may cause response desynchronization in deployments that rely on the incorrect Content-Length value. This issue has been patched in versions 2.2.23, 3.1.21, and 3.2.6.

Title
Heap overflow in libnv
Summary
When processing the header of an incoming message, libnv failed to properly validate the message size.
The lack of validation allows a malicious program to write outside the bounds of a heap allocation. This can trigger a crash or system panic, and it may be possible for an unprivileged user to exploit the bug to elevate their privileges.

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.

CVE-2026-40199 (GCVE-0-2026-40199)

Title
Net::CIDR::Lite versions before 0.23 for Perl mishandles IPv4 mapped IPv6 addresses, which may allow IP ACL bypass
Summary
Net::CIDR::Lite versions before 0.23 for Perl mishandles IPv4 mapped IPv6 addresses, which may allow IP ACL bypass.
_pack_ipv6() includes the sentinel byte from _pack_ipv4() when building the packed representation of IPv4 mapped addresses like ::ffff:192.168.1.1. This produces an 18 byte value instead of 17 bytes, misaligning the IPv4 part of the address.
The wrong length causes incorrect results in mask operations (bitwise AND truncates to the shorter operand) and in find() / bin_find() which use Perl string comparison (lt/gt). This can cause find() to incorrectly match or miss addresses.
Example:
my $cidr = Net::CIDR::Lite->new("::ffff:192.168.1.0/120");
$cidr->find("::ffff:192.168.2.0"); # incorrectly returns true
This is triggered by valid RFC 4291 IPv4 mapped addresses (::ffff:x.x.x.x).
See also CVE-2026-40198, a related issue in the same function affecting malformed IPv6 addresses.

CVE-2026-41035 (GCVE-0-2026-41035)
Vulnerability from cvelistv5 – Published: 2026-04-16 06:53 – Updated: 2026-04-22 03:03
VLAI
Summary
In rsync 3.0.1 through 3.4.1, receive_xattr relies on an untrusted length value during a qsort call, leading to a receiver use-after-free. The victim must run rsync with -X (aka --xattrs). On Linux, many (but not all) common configurations are vulnerable. Non-Linux platforms are more widely vulnerable.
Severity
7.4 (High)

Title
rust-openssl: Unchecked callback-returned length in PSK and cookie generate trampolines can cause OpenSSL to leak adjacent memory to the network peer
Summary
rust-openssl provides OpenSSL bindings for the Rust programming language. From 0.9.24 to before 0.10.78, the FFI trampolines behind SslContextBuilder::set_psk_client_callback, set_psk_server_callback, set_cookie_generate_cb, and set_stateless_cookie_generate_cb forwarded the user closure's returned usize directly to OpenSSL without checking it against the &mut [u8] that was handed to the closure. This can lead to buffer overflows and other unintended consequences. This vulnerability is fixed in 0.10.78.

Title
mouse07410/asn1c: 1-byte Heap Out-of-Bounds Read in `INTEGER_decode_oer` via Malformed OER Payload
Summary
mouse07410/asn1c is an ASN.1 compiler. In 1.4 and earlier, a memory safety vulnerability was identified in the OER decoding skeleton files generated by asn1c (specifically INTEGER_oer.c). When parsing a maliciously crafted, zero-length OER payload for a variable-length, non-negative INTEGER type, the decoder fails to validate the required bytes before extracting the Most Significant Bit (MSB). This forces a precise 1-byte Heap Out-of-Bounds (OOB) Read. Because asn1c generated code is primarily deployed to parse untrusted network inputs (such as V2X network protocols, 5G telecom headers, or X.509 certificates), when the decoder processes untrusted network-originated input, a remote attacker can exploit this to cause a Denial of Service (DoS) or trigger incorrect integer interpretation in downstream applications (e.g., protocol state poisoning or logic bypass).

Title
Ovn: ovn: heap over-read in icmp error response generation - security issue
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-2026-5367 (GCVE-0-2026-5367)
Vulnerability from cvelistv5 – Published: 2026-04-24 12:25 – Updated: 2026-05-29 12:45

Title
Ovn: ovn: information disclosure via crafted dhcpv6 packets
Summary
A flaw was found in OVN (Open Virtual Network). A remote attacker, by sending crafted DHCPv6 (Dynamic Host Configuration Protocol for IPv6) SOLICIT packets with an inflated Client ID length, could cause the ovn-controller to read beyond the bounds of a packet. This out-of-bounds read can lead to the disclosure of sensitive information stored in heap memory, which is then returned to the attacker's virtual machine port.
Severity
8.6 (High)
CWE
- CWE-130 - Improper Handling of Length Parameter Inconsistency

Title
Potential denial-of-service vulnerability in ASGI requests via file upload limit bypass
Summary
An issue was discovered in 6.0 before 6.0.5 and 5.2 before 5.2.14.
ASGI requests with a missing or understated `Content-Length` header can bypass the `FILE_UPLOAD_MAX_MEMORY_SIZE` limit, potentially loading large files into memory and causing service degradation.
As a reminder, Django expects a limit to be configured at the web server level rather than solely relying on `FILE_UPLOAD_MAX_MEMORY_SIZE`.
Earlier, unsupported Django series (such as 5.0.x, 4.1.x, and 3.2.x) were not evaluated and may also be affected.
Django would like to thank Kyle Agronick for reporting this issue.

Mitigation
Phase: Implementation
Description:
- 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
Phase: Implementation
Description:
- Do not let the user control the size of the buffer.
Mitigation
Phase: Implementation
Description:
- 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.
