# CVE-2023-4863

State: PUBLISHED
Published: 2023-09-12

**Severity:** CVSS 3.1: 8.8 (HIGH) CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

**CISA KEV:** listed - added 2023-09-13, remediation due 2023-10-04 (Google Chromium WebP Heap-Based Buffer Overflow Vulnerability). This is known to be exploited in the wild.

**Affected versions (NVD):**
- google chrome: before 116.0.5845.187
- webmproject libwebp: before 1.3.2
- fedoraproject fedora: 37
- fedoraproject fedora: 38
- fedoraproject fedora: 39
- debian debian linux: 10.0

## Description
Heap buffer overflow in libwebp in Google Chrome prior to 116.0.5845.187 and libwebp 1.3.2 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: Critical)

## Affected (as published in the CVE record)
- Google Chrome: from 116.0.5845.187 before 116.0.5845.187 (affected)
- Google libwebp: from 1.3.2 before 1.3.2 (affected)

=== [4] THINKING (7s) ===
The user asked about CVE-2023-4863 affecting OpenSSH. But the lookup shows this CVE is actually about a **libwebp heap buffer overflow in Google Chrome**, not OpenSSH at all. This is a mismatch — the user may be confusing CVE numbers, or testing me.

Let me be careful and honest here. The authoritative source says CVE-2023-4863 is a libwebp/Chrome vulnerability, not an OpenSSH one. I should not fabricate OpenSSH details. I should report what the CVE actually is, and note that it does not affect OpenSSH.

Let me double check — maybe the user is thinking of a different CVE for OpenSSH. There are known OpenSSH CVEs. But I shouldn't guess. Let me just report accurately what CVE-2023-4863 is, and clarify it's not an OpenSSH vulnerability.

Actually, let me reconsider. The description clearly states it's a libwebp heap buffer overflow in Google Chrome. This is definitively NOT an OpenSSH issue. I must correct the premise rather than make up OpenSSH version ranges and CVSS scores.

I'll be direct: this CVE does not affect OpenSSH. Provide the real details.

=== [5] ASSISTANT TEXT ===
I need to flag something important before answering: **CVE-2023-4863 does not affect OpenSSH.** That premise doesn't match the authoritative CVE record.

## What CVE-2023-4863 actually is

It's a **heap buffer overflow in libwebp (the WebP image codec) as shipped in Google Chrome**, published 2023‑09‑12.

- **Description:** A remote attacker can perform an out-of-bounds memory write via a crafted HTML page (Chromium severity: Critical).
- **Affected products (per the NVD record):**
  - Google Chrome: before **116.0.5845.187**
  - libwebp: before **1.3.2**
  - Fedora 37/38/39, Debian 10 (as affected distributions of the bundled libwebp)
- **CVSS 3.1 score:** **8.8 (HIGH)** — `AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H`
- **CISA KEV status:** ✅ **Listed** — added 2023‑09‑13, remediation due 2023‑10‑04, and flagged as **known to be exploited in the wild**.

So there is no "vulnerable OpenSSH version range" for this CVE — OpenSSH simply isn't one of the affected components.

## A note on the KEV entry

One thing worth flagging from the lookup output: the KEV line's *title text* ("Google Chromium WebP Heap-Based Buffer Overflow") matches this vulnerability, which is consistent. But the fact that a browser codec CVE carries a CISA KEV entry with an exploitation-in-the-wild flag is unusual for a libwebp issue — that language is more typical of network-exploitable bugs. If you're doing incident response or patching, I'd recommend confirming directly against CISA's KEV catalog rather than relying solely on this summary, since the metadata here looks slightly inconsistent.

## Possible confusion

You may be thinking of a different identifier. If you're actually looking for an **OpenSSH** vulnerability, tell me what you remember (roughly when, the symptom, or any partial CVE number) and I'll look up the correct one. Some well-known OpenSSH CVEs exist, but I don't want to guess at a number and hand you the wrong data.

Which is it — do you want me to hunt down the specific OpenSSH CVE you have in mind?
