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...

MITKRB5-SA-2005-002: buffer overflow, heap corruption in KDC

-----BEGIN PGP SIGNED MESSAGE----- MIT krb5 Security Advisory 2005-002 Original release: 2005-07-12 Topic: buffer overflow, heap corruption in KDC Severity: CRITICAL SUMMARY ======= The MIT krb5 Key Distribution Center KDC implementation can corrupt the heap by attempting to free memory at a rand...

Fedora Core 4 : krb5-1.4.1-5 (2005-553)

A double-free flaw was found in the krb5recvauth routine which may be triggered by a remote unauthenticated attacker. Fedora Core 4 contains checks within glibc that detect double-free flaws. Therefore, on Fedora Core 4, successful exploitation of this issue can only lead to a denial of service K...
