Astra Linux – Vulnerability in krb5

A vulnerability in the MIT Kerberos implementation allows for GSSAPI-protected messages that use RC4-HMAC-MD5 to be spoofed, due to weaknesses in the MD5 checksum design. If RC4 is preferred over stronger encryption methods, an attacker could exploit MD5 collisions to forge message integrity code...
