Fedora: krb5 double-free bugs (Core 2)
Summary
Kerberos V5 is a trusted-third-party network authentication system,
which can improve your network's security by eliminating the insecure
practice of cleartext passwords.
Update Information:
Kerberos is a networked authentication system which 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 does not affect Fedora Core.
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.
