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.
