Detail
| Problem Description: Updated Kerberos (krb5) packages that correct double-free and ASN.1 parsing bugs are now available for Red Hat Enterprise Linux. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386 3. Problem description: Kerberos is a networked authentication system that uses a trusted third party (a KDC) to authenticate clients and servers to each other. Several double-free bugs were found in the Kerberos 5 KDC and libraries. A remote attacker could potentially exploit these flaws to execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2004-0642 and CAN-2004-0643 to these issues. A double-free bug was also found in the krb524 server (CAN-2004-0772), however this issue was fixed for Red Hat Enterprise Linux 2.1 users by a previous erratum, RHSA-2003:052. An infinite loop bug was found in the Kerberos 5 ASN.1 decoder library. A remote attacker may be able to trigger this flaw and cause a denial of service. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0644 to this issue. All users of krb5 should upgrade to these updated packages, which contain backported security patches to resolve these issues. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ 5. Bug IDs fixed (http://bugzilla.redhat.com/ for more info): 129680 - Upgrading to krb5-libs 1.2.2-27 can cause undefined symbol __dn_expand |

Open Source Vulnerability Database (OSVDB)
| Id | Description |
|---|---|
| 9409 | MIT Kerberos 5 krb524d Double-free Error Condition Code Execution MIT Kerberos contains a flaw that may allow a malicious user to execute arbitrary commands. The issue is due to a double-free condition inside the Key Distribution Center (KDC) code. Under some circumstances, a KDC host could be compromised by a remote attacker. No further details have been provided. |
| 9408 | MIT Kerberos 5 krb524d krb5_rd_cred() Arbitrary Code Execution Keberos contains a flaw that may allow a malicious user to execute arbitrary commaands. The issue is triggered when krb5_rd_cread() tries to free allready freed buffers that were returned by decode_krb5_enc_cred_part() when error occurs. It is possible that the flaw may allow compromise entire Kerberos realm if victim is running KDC resulting in a loss of integrity. |
| 9407 | MIT Kerberos 5 Double-free Error Condition Code Execution MIT Kerberos 5 contains a flaw related to a double free in the KDC ASN.1 error handling code that may allow an attacker to run privileged code of the attackers choosing. MIT note that no published means of exploiting a double free is known, impying that a real world exploit would be difficult at best. Should this feat be achieved, a complete Kerberos realm could be compromised. |
| 9406 | MIT Kerberos 5 ASN.1 Decoder DoS MIT Kerberos 5 distribution contains a flaw that may allow a remote denial of service. The issue is triggered when an attacker impersonating a legitimate key distribution center or application server may cause a client program to hang inside an infinite loop via a specially crafted BER encoding and will result in loss of availability of the service. |
