Two information disclosure vulnerabilities were discovered in Apport and core-dump handler, affecting Ubuntu, Fedora, and Red Hat.
The vulnerabilities, CVE-2025-5054 and CVE-2025-4598, are race condition bugs that allow threat actors to access sensitive information.
Mitigations are available for the vulnerabilities, advising users to secure core dumps, implement strict PID validation, and enforce restrictions on accessing SUID/SGID core files.
Qualys developed proof-of-concept for both vulnerabilities and system administrators are urged to take necessary security measures.
