CVE-2024-24786

A flaw was found in golang-protobuf. The protojson unmarshaling function can enter an infinite loop when parsing certain invalid JSON inputs, specifically when decoding messages containing Any values or when configured to discard unknown fields. A remote attacker can exploit this vulnerability by submitting specially crafted JSON payloads to cause excessive CPU utilization and hang the application, resulting in a Denial of Service (DoS).

CVE-2026-61801

A flaw was found in the moby/sys/user package. The package does not properly limit memory allocation when parsing Unix-style user and group database files, such as /etc/passwd or /etc/group. An attacker who can supply a specially crafted file can cause excessive memory consumption, leading to a Denial of Service (DoS) condition by crashing the affected process.

CVE-2026-61801 (GCVE-0-2026-61801)

Vulnerability from cvelistv5 – Published: 2026-10-08 16:22 – Updated: 2026-10-08 17:27

Title

github.com/moby/sys/user has a possible DoS via unbounded parsing of user and group database files

Summary

The `github.com/moby/sys/user` package provides Go utilities for parsing and looking up entries in Unix-style user and group database files. Versions before 0.4.1 do not sufficiently limit entries when parsing `/etc/passwd`- or `/etc/group`-style files, allowing an attacker who can supply a specially crafted file to cause excessive memory consumption and potentially terminate the affected process due to an out-of-memory condition. This issue is patched in version 0.4.1. As a workaround, avoid parsing attacker-controlled user or group database files, or validate and limit untrusted input before parsing it.

Severity

5.5 (Medium)
