Ubuntu 4.10 / 5.04 : krb4, krb5 vulnerabilities (USN-224-1)
Gael Delalleau discovered a buffer overflow in the envoptadd function of the Kerberos 4 and 5 telnet clients. By sending specially crafted replies, a malicious telnet server could exploit this to execute arbitrary code with the privileges of the user running the telnet client. CVE-2005-0468 Gael...
Ubuntu 4.10 : krb5 vulnerability (USN-58-1)
Michael Tautschnig discovered a possible buffer overflow in the addtohistory function in the MIT Kerberos 5 implementation. Performing a password change did not properly track the password policy's history count and the maximum number of keys. This could cause an array overflow and may have allow...
