Gentoo Linux Advisory: HeimdalMay 28, 2004, 00:13 (0 Talkback[s])
Gentoo Linux Security Advisory GLSA 200405-23
A possible buffer overflow in the Kerberos 4 component of Heimdal has been discovered.
Heimdal is a free implementation of Kerberos.
Package / Vulnerable / Unaffected
1 app-crypt/heimdal < 0.6.2 >= 0.6.2
A buffer overflow was discovered in kadmind, a server for administrative access to the Kerberos database.
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.
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.
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"
