Exploitation evidence

Disclosed: evidence found.
CVE published 7 May 2024
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.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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 2026-10-26.

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.

What to do

Upgrade debian/glib to 2.80.1 or 2.78.5.

AI-suggested

Red Hat has released updated glib2 packages for Red Hat Enterprise Linux 8.2 AUS that address these vulnerabilities. Users should apply these official security updates promptly following Red Hat's guidance at https://access.redhat.com/articles/11258. No additional mitigation steps are indicated by the vendor advisory. Systems running affected versions should be updated to the fixed package versions to remediate these issues.

Description

This release of the Red Hat OpenShift distributed tracing platform (Jaeger) provides security improvements. Breaking changes: * Nothing Deprecations: * Nothing Technology Preview features: * Nothing Enhancements: * Nothing Bug fixes: * https://access.redhat.com/security/cve/CVE-2025-4373 * https://access.redhat.com/security/cve/CVE-2024-34397 * https://access.redhat.com/security/cve/CVE-2024-52533 Known issues: * Nothing

Impact

The identified vulnerabilities could potentially allow attackers to cause memory corruption issues such as buffer overflow and underflow, and exploit signal subscription weaknesses in GLib2. This could lead to application instability or other security impacts depending on the context of use. However, Red Hat rates the overall impact as moderate, and there are no known exploits in the wild at this time.

Summary

The GLib2 library, which provides core application building blocks for C libraries and applications including GNOME components, has multiple security flaws. These include signal subscription vulnerabilities (CVE-2024-34397), a buffer overflow vulnerability in the set_connect_msg() function (CVE-2024-52533), and a buffer underflow vulnerability in the g_string_insert_unichar function (CVE-2025-4373). These vulnerabilities affect Red Hat Enterprise Linux 8.2 AUS and related packages. Red Hat has released security updates to address these issues, with advisories RHSA-2025:14991 and RHSA-2025:11662 providing details and update instructions. The vulnerabilities have been assessed as moderate in severity, and no active exploitation has been reported.

CWE-940Improper Verification of Source of a Communication Channel (opens in a new tab)
Base weaknessOWASP Top 10 A07:2025: Authentication Failures (opens in a new tab)
The product establishes a communication channel to handle an incoming request that has been initiated by an actor, but it does not properly verify that the request is coming from the expected origin.
Architecture and Design
Use a mechanism that can validate the identity of the source, such as a certificate, and validate the integrity of data to ensure that it cannot be modified in transit using an Adversary-in-the-Middle (AITM) attack.

CWE-193Off-by-one Error (opens in a new tab)
Base weakness
A product calculates or uses an incorrect maximum or minimum value that is 1 more, or 1 less, than the correct value.
Implementation
When copying character arrays or using character manipulation methods, the correct size parameter must be used to account for the null terminator that needs to be added at the end of the array.

CWE-124Buffer Underwrite ('Buffer Underflow') (opens in a new tab)
Base weaknessLikelihood of exploit: Medium
The product writes to a buffer using an index or pointer that references a memory location prior to the beginning of the buffer.
Requirements
Choose a language that is not susceptible to these issues.
Implementation
All calculated values that are used as index or for pointer arithmetic should be validated to ensure that they are within an expected range.
