CentOS Update for krb5-devel CESA-2008:0181 centos3 i386

Check for the Version of krb5-devel

Kerberos is a network authentication system which allows clients and servers to authenticate to each other through use of symmetric encryption and a trusted third party, the KDC. A flaw was found in the way the MIT Kerberos Authentication Service and Key Distribution Center server (krb5kdc) handled Kerberos v4 protocol packets. An unauthenticated remote attacker could use this flaw to crash the krb5kdc daemon, disclose portions of its memory, or possibly execute arbitrary code using malformed or truncated Kerberos v4 protocol requests. (CVE-2008-0062, CVE-2008-0063) This issue only affected krb5kdc with Kerberos v4 protocol compatibility enabled, which is the default setting on Red Hat Enterprise Linux 4. Kerberos v4 protocol support can be disabled by adding &quot v4_mode=none&quot (without the quotes) to the &quot [kdcdefaults]&quot section of /var/kerberos/krb5kdc/kdc.conf. A flaw was found in the RPC library used by the MIT Kerberos kadmind server. An unauthenticated remote attacker could use this flaw to crash kadmind. This issue only affected systems with certain resource limits configured and did not affect systems using default resource limits used by Red Hat Enterprise Linux 2.1 or 3. (CVE-2008-0948) Red Hat would like to thank MIT for reporting these issues. All krb5 users are advised to update to these erratum packages which contain backported fixes to correct these issues.
