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

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 26 Oct 2026.

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 the Red Hat redhat/libtiff package to 9.6.

AI-suggested

A security update for libtiff is available from Red Hat addressing CVE-2025-8176 and CVE-2025-9900. Users of affected Red Hat Enterprise Linux 9 and related distributions should apply the update as per Red Hat's advisory RHSA-2025:19113. Refer to https://access.redhat.com/articles/11258 for detailed update instructions. No additional mitigation steps are indicated by the vendor.

Description

Two security vulnerabilities have been identified in the libtiff library used for manipulating TIFF files: a Use-After-Free vulnerability (CVE-2025-8176) and a Write-What-Where vulnerability (CVE-2025-9900). These vulnerabilities affect various Red Hat Enterprise Linux 9 and related distributions. A security update is available to address these issues. The vulnerabilities have been rated with high severity by the vendor. No known exploits are reported in the wild at this time.

Impact

The vulnerabilities in libtiff could allow attackers to exploit memory corruption issues, potentially leading to arbitrary code execution or system compromise. The vendor rates the security impact as Important (high severity). There are no reports of known exploits in the wild at this time.

Summary

The libtiff library contains two security flaws: CVE-2025-8176, a Use-After-Free vulnerability, and CVE-2025-9900, a Write-What-Where vulnerability. Both vulnerabilities could potentially allow an attacker to manipulate memory in unintended ways, leading to possible security breaches. These issues affect multiple Red Hat Enterprise Linux 9 variants and related packages. Red Hat has released security updates to fix these vulnerabilities, as detailed in their advisory RHSA-2025:19113. The vulnerabilities are tracked under CWE-825 (Use After Free) and CWE-123 (Write-What-Where).

CWE-825Expired Pointer Dereference (opens in a new tab)
Base weakness
The product dereferences a pointer that contains a location for memory that was previously valid, but is no longer valid.
Architecture and Design
Choose a language that provides automatic memory management.
Implementation
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.

CWE-123Write-what-where Condition (opens in a new tab)
Base weaknessLikelihood of exploit: High
Any condition where the attacker has the ability to write an arbitrary value to an arbitrary location, often as the result of a buffer overflow.
Architecture and Design · Language Selection
Use a language that provides appropriate memory abstractions.
Operation
Use OS-level preventative functionality integrated after the fact. Not a complete solution.
