Kerberos AES and RC4 Decryption Integer Underflow Vulnerabilities

Multiple vulnerabilities have been identified in Kerberos, which could be exploited by remote attackers to cause a denial of service or compromise a vulnerable system. These issues are caused by integer underflow errors in the AES and RC4 decryption operations when processing an invalid ciphertext, which could be exploited by remote unauthenticated attackers to crash KDC or execute arbitrary code.
