Apache in macOS Mojave before Security Update 2021-004 had multiple unspecified vulnerabilities that could allow local system termination or kernel memory read.
Vulnerability
Multiple issues exist in the Apache version shipped with macOS Mojave before Security Update 2021-004 (corresponding to Apache 2.4.46). The official advisory [1] states that a logic issue was addressed with improved state management, but does not disclose further technical details about the specific code path or conditions required to trigger these issues.
Exploitation
According to Apple's security content [1], exploitation requires local access to the system. The exact attack vector and sequence of steps are not detailed in the available references, but a local user could trigger the vulnerability.
Impact
A local user may be able to cause unexpected system termination or read kernel memory [1]. This indicates potential for both denial of service (via system termination) and information disclosure (kernel memory read).
Mitigation
The issue is fixed in Security Update 2021-004 Mojave, released on May 24, 2021 [1]. Users should apply the update via macOS Software Update. No workaround other than applying the recommended patch is mentioned.
