Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer, where the product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. this may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. In Github.com/omec project/amf, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A vulnerability was identified in omec-project amf up to 2.1.3-dev. The affected element is an unknown function of the file ngap/dispatcher.go of the component NGAP Message Handler. The manipulation leads to memory corruption. The attack may be initiated remotely. The exploit is publicly available and might be used. Upgrading to version 2.2.0 is sufficient to fix this issue. It is suggested to upgrade the affected component. The same pull request fixes multiple security issues.
