Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

Description

CVE-2024-34158 is a vulnerability involving stack exhaustion in the Parse function within the go/build/constraint package. The issue is categorized under CWE-674, which relates to uncontrolled recursion leading to resource exhaustion. The vulnerability affects certain versions of Microsoft-related software including versions 2.0 and 3.0, as well as Azure Linux and CBL Mariner 2.0. No CVSS score or detailed impact information is provided, and there are no known exploits in the wild. No patch or remediation guidance is currently available from the vendor.

Impact

The vulnerability could potentially allow an attacker to cause a denial of service by exhausting the stack through the Parse function. However, no specific impact details or exploitation reports are available. Without further information, the exact consequences remain unclear.

Summary

This vulnerability, CVE-2024-34158, concerns a stack exhaustion condition in the Parse function of the go/build/constraint package used by Microsoft products. The flaw is classified as CWE-674, indicating that uncontrolled recursion or excessive stack usage can lead to exhaustion of stack memory. Affected products include Microsoft software versions 2.0 and 3.0, Azure Linux, and CBL Mariner 2.0. The vendor has not provided a patch or detailed advisory information, and no exploit activity has been reported.

CWE-674Uncontrolled Recursion (opens in a new tab)
Class weakness
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
Implementation
Ensure that an end condition will be reached under all logic conditions. The end condition may include checking against the depth of recursion and exiting with an error if the recursion goes too deep. The complexity of the end condition contributes to the effectiveness of this action.
Implementation
Increase the stack size.
Attack patterns
Serialized Data with Nested Payloads (opens in a new tab)
Oversized Serialized Data Payloads (opens in a new tab)
From MITRE CWE, MITRE CAPEC and OWASP (Top 10, OpenCRE).
