CVE-2026-95512: Uncontrolled Resource Consumption in Red Hat Red Hat Hardened Images
A flaw was found in FreeType, specifically within its CID font loader. A remote attacker could exploit this vulnerability by tricking a user into opening content that embeds or references a specially crafted CID-keyed font. This crafted font can cause repeated allocations and decryptions of subroutine data across multiple font dictionaries, leading to excessive memory and CPU consumption. This can result in a denial of service (DoS) for the application or service processing the font, potentially causing it to hang or terminate.
AI Analysis
Technical Summary
This vulnerability exists in the CID font loader component of FreeType, as used in Red Hat's OpenJDK 11 ELS. An attacker can exploit it by embedding or referencing a maliciously crafted CID-keyed font in content that a user opens. The crafted font triggers repeated allocations and decryptions of subroutine data across multiple font dictionaries, causing uncontrolled resource consumption (memory and CPU). This can lead to denial of service conditions for the application or service processing the font.
Potential Impact
The impact is denial of service (DoS) due to excessive memory and CPU consumption, potentially causing the affected application or service to hang or terminate. There is no impact on confidentiality or integrity reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the Red Hat advisory at https://access.redhat.com/security/cve/CVE-2026-95512 for current remediation guidance. No specific mitigation or workaround is provided in the available data.
