"Updated Kerberos (krb5) packages that correct double-free and ASN.1

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 CVE-2004-0642 and
CVE-2004-0643 to these issues.

A double-free bug was also found in the krb524 server (CVE-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 CVE-2004-0644 to this issue.

All users of krb5 should upgrade to these updated packages, which
contain backported security patches to resolve these issues."

exist in the krb5 library code, which makes client programs and
application servers vulnerable. The MIT Kerberos 5 development team
believes that exploitation of these bugs would be difficult and no
known vulnerabilities are believed to exist. The vulnerability in
krb524d was discovered by Marc Horowitz; the other double-free
vulnerabilities were discovered by Will Fiveash and Nico Williams at
Sun.

Will Fiveash and Nico Williams also found another vulnerability in the
ASN.1 decoder library. This makes krb5 vulnerable to a DoS (Denial of
Service) attack causing an infinite loop in the decoder. The KDC is
vulnerable to this attack.

The MIT Kerberos 5 team has provided patches which have been applied
to the updated software to fix these issues. Mandrakesoft encourages
all users to upgrade immediately."

"The remote host is affected by the vulnerability described in GLSA-200409-09
(MIT krb5: Multiple vulnerabilities)

    The implementation of the Key Distribution Center (KDC) and the MIT krb5
    library contain double-free vulnerabilities, making client programs as well
    as application servers vulnerable.
    The ASN.1 decoder library is vulnerable to a denial of service attack,
    including the KDC.
  
Impact :

    The double-free vulnerabilities could allow an attacker to execute
    arbitrary code on a KDC host and hosts running krb524d or vulnerable
    services. In the case of a KDC host, this can lead to a compromise of the
    entire Kerberos realm. Furthermore, an attacker impersonating a legitimate
    KDC or application server can potentially execute arbitrary code on
    authenticating clients.
    An attacker can cause a denial of service for a KDC or application server
    and clients, the latter if impersonating a legitimate KDC or application
    server.
  
Workaround :

    There is no known workaround at this time."

"Updated krb5 packages that improve client responsiveness and fix
several security issues are now available for Red Hat Enterprise Linux
3.

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 CVE-2004-0642 and
CVE-2004-0643 to these issues.

A double-free bug was also found in the krb524 server (CVE-2004-0772),
however this issue does not affect Red Hat Enterprise Linux 3 Kerberos
packages.

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 CVE-2004-0644 to this issue.

When attempting to contact a KDC, the Kerberos libraries will iterate
through the list of configured servers, attempting to contact each in
turn. If one of the servers becomes unresponsive, the client will time
out and contact the next configured server. When the library attempts
to contact the next KDC, the entire process is repeated. For
applications which must contact a KDC several times, the accumulated
time spent waiting can become significant.

This update modifies the libraries, notes which server for a given
realm last responded to a request, and attempts to contact that server
first before contacting any of the other configured servers.

All users of krb5 should upgrade to these updated packages, which
contain backported security patches to resolve these issues."
