CVE-2024-4761
Description
An out-of-bounds write vulnerability was found in the Chromium web browser. If a remote, unauthenticated attacker tricks a user into visiting a specially crafted HTML page, the attacker could write to memory, which is out of bounds. This issue could have impacts to integrity, availability, and confidentiality.
Statement
Chromium is not shipped in any supported Red Hat offerings.
Mitigation
Until updated packages are released for Fedora and EPEL, consider temporarily swapping to an alternative web browser such as Firefox or severely restricting activity to sites you know well and trust.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.

Understanding the Weakness (CWE)
Integrity
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Write operations could cause memory corruption. In some cases, an adversary can modify control data such as return addresses in order to execute unexpected code.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
Attempting to access out-of-range, invalid, or unauthorized memory could cause the product to crash.
Other
Technical Impact: Unexpected State
Subsequent write operations can produce undefined or unexpected results.
