AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
An out-of-bounds read in macOS Mojave before 10.14.3 could allow an application to read restricted memory.
Vulnerability
An out-of-bounds read vulnerability exists in macOS Mojave versions prior to 10.14.3. The issue was addressed with improved input validation. The exact component is not disclosed in the available references, but the vulnerability allows an application to read restricted memory. [1]
Exploitation
An attacker would need to trick a user into running a malicious application on the affected system. No additional privileges are required beyond the ability to execute code as a user. The application can then read restricted memory out of bounds.
Impact
Successful exploitation leads to information disclosure of restricted memory, potentially exposing sensitive data such as passwords, encryption keys, or other confidential information. The attacker gains unauthorized read access to memory regions that should be protected.
Mitigation
Apple has fixed this issue in macOS Mojave 10.14.3, released on January 22, 2019. Users should upgrade to this version or later. No workarounds are available. [1]
