Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

CVE-2009-4212 krb: KDC integer overflows in AES and RC4 decryption
routines (MITKRB5-SA-2009-004)

Multiple integer underflow flaws, leading to heap-based corruption,
were found in the way the MIT Kerberos Key Distribution Center (KDC)
decrypted ciphertexts encrypted with the Advanced Encryption Standard
(AES) and ARCFOUR (RC4) encryption algorithms. If a remote KDC client
were able to provide a specially crafted AES- or RC4-encrypted
ciphertext or texts, it could potentially lead to either a denial of
service of the central KDC (KDC crash or abort upon processing the
crafted ciphertext), or arbitrary code execution with the privileges
of the KDC (i.e., root privileges). (CVE-2009-4212)

All running services using the MIT Kerberos libraries must be
restarted for the update to take effect.
