CVE-2025-3576: Red Hat Discovery 2
Medium severity, CVSS 5.9. EPSS: 0.3% chance of exploitation in the next 30 days.
A vulnerability in the MIT Kerberos implementation allows GSSAPI-protected messages using RC4-HMAC-MD5 to be spoofed due to weaknesses in the MD5 checksum design. If RC4 is preferred over stronger encryption types, an attacker could exploit MD5 collisions to forge message integrity codes. This may lead to unauthorized message tampering.
