Severity: High Title: Heimdal: Kerberos 4 buffer overflow in kadmin Date: May 27, 2004 Bugs: #50208 ID: 200405-23
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis ========
A possible buffer overflow in the Kerberos 4 component of Heimdal has been discovered.
Background ==========
Heimdal is a free implementation of Kerberos.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-crypt/heimdal < 0.6.2 >= 0.6.2
Description ===========
A buffer overflow was discovered in kadmind, a server for administrative access to the Kerberos database.
Impact ======
By sending a specially formatted message to kadmind, a remote attacker may be able to crash kadmind causing a denial of service, or execute arbitrary code with the permissions of the kadmind process.
Workaround ==========
For a temporary workaround, providing you do not require Kerberos 4 support, you may turn off Kerberos 4 kadmin by running kadmind with the --no-kerberos4 option.
Resolution ==========
All Heimdal users should upgrade to the latest stable version:
# emerge sync
# emerge -pv ">=app-crypt/heimdal-0.6.2" # emerge ">=app-crypt/heimdal-0.6.2"
