Common Weakness Enumeration

CWE-198

Allowed

Use of Incorrect Byte Ordering

Abstraction: Variant · Status: Draft

API response cwe.mitre.org

The product receives input from an upstream component, but it does not account for byte ordering (e.g. big-endian and little-endian) when processing the input, causing an incorrect number or value to be used.

3 vulnerabilities reference this CWE, most recent first.

Title
Junos OS: SRX300 Series: rpd will crash upon receiving a specific, valid BGP UPDATE message
Summary
A Use of Incorrect Byte Ordering vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS on SRX300 Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). When a BGP update is received over an established BGP session which contains a specific, valid, optional, transitive path attribute, rpd will crash and restart. This issue affects eBGP and iBGP over IPv4 and IPv6. This issue affects: Junos OS: * 22.1 versions from 22.1R1 before 22.2R3-S4, * 22.3 versions before 22.3R3-S3, * 22.4 versions before 22.4R3-S2, * 23.2 versions before 23.2R2, * 23.4 versions before 23.4R2.

Vulnerability from github – Published: 2021-08-25 20:53 – Updated: 2023-06-13 20:30
VLAI
Summary
Soundness issue in raw-cpuid
Details

VendorInfo::as_string(), SoCVendorBrand::as_string(), and ExtendedFunctionInfo::processor_brand_string() construct byte slices using std::slice::from_raw_parts(), with data coming from #[repr(Rust)] structs. This is always undefined behavior. This flaw has been fixed in v9.0.0, by making the relevant structs #[repr(C)].

Severity
7.5 (High)

A Use of Incorrect Byte Ordering

vulnerability

in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS on SRX300 Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).

When a BGP update is received over an established BGP session which contains a specific, valid, optional, transitive path attribute, rpd will crash and restart.

This issue affects eBGP and iBGP over IPv4 and IPv6.

This issue affects:

Junos OS:

  • 22.1 versions from 22.1R1 before 22.2R3-S4,
  • 22.3 versions before 22.3R3-S3,
  • 22.4 versions before 22.4R3-S2,
  • 23.2 versions before 23.2R2,
  • 23.4 versions before 23.4R2.
