Synopsis

The remote Scientific Linux host is missing one or more security updates.

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.

Solution

Update the affected packages.
