Kerberos libkadm5srv buffer overflow
| kerberos-libkadm5srv-bo (18621) |  High Risk |
Description:
Kerberos is vulnerable to a heap-based buffer overflow in the libkadm5srv administration library, caused by a vulnerability in the password history handling code. Under certain conditions, a remote authenticated attacker could overflow a buffer and execute arbitrary code on the system.
Consequences:
Gain Access
Remedy:
Upgrade to the latest version of Kerberos (krb5-1.4 or krb5-1.3.6 or later), when it becomes available from the MIT Kerberos Web site. See References.
—OR—
Apply the 2004-004-patch_1.3.5, available from the MIT Kerberos Web site. See References.
For Trustix Secure Linux:
