CVE-2003-0139

The connected Debian advisory (DSA-266-1) confirms CVE-2003-0139 concerns MIT Kerberos 4 (krb4) weaknesses in the krb5 distribution. Specifically, when using triple-DES keys to protect krb4 services, an attacker can craft krb4 tickets for unauthorized principals via a cut-and-paste/ticket-splicin...

MIT Kerberos vulnerable to ticket splicing when using Kerberos4 triple DES service tickets

Overview Several cryptographic vulnerabilities exist in the basic Kerberos version 4 protocol that could allow an attacker to impersonate any user in a Kerberos realm and gain any privilege authorized through that Kerberos realm. Description The MIT Kerberos Development team has discovered a...

MITKRB5-SA-2003-004: Cryptographic weaknesses in Kerberos v4 protocol

-----BEGIN PGP SIGNED MESSAGE----- MIT krb5 Security Advisory 2003-004 2003-03-17 Topic: Cryptographic weaknesses in Kerberos v4 protocol Severity: CRITICAL SUMMARY ======= A cryptographic weakness in version 4 of the Kerberos protocol allows an attacker to use a chosen-plaintext attack to...

SSH ssh-keygen with Secure-RPC SUN-DES-1 Phrase Recovery

The remote host is running a version of SSH Communications Security SSH comprised between versions 1.2.27 and 1.2.30. With Secure-RPC, this version can allow local attackers to recover a SUN-DES-1 magic phrase generated by another user, which the attacker can use to decrypt that user's private ke...

VNC authentication weakness

VNC authentication weakness --------------------------- VNC uses a DES-encrypted challenge-response system to avoid passing passwords over the wire in plaintext. However, it seems that a weakness in the way the challenge is generated by some servers would make this useless. The following program...

CVE-1999-1100

CVE-1999-1100 affects Cisco PIX Private Link 4.1.6 and earlier. The vulnerability arises because certain configuration-file commands cause the DES key length to effectively shrink from 56 bits to 48 bits, easing brute-force key discovery. This is the root cause and the primary impact described in...

CVE-1999-1100

Cisco PIX Private Link 4.1.6 and earlier does not properly process certain commands in the configuration file, which reduces the effective key length of the DES key to 48 bits instead of 56 bits, which makes it easier for an attacker to find the proper key via a brute force attack...

CVE-2001-0856

The CVE-2001-0856 entry concerns IBM 4758 cryptographic hardware (CCA). The affected component is the CCA functionality used to protect DES/3DES keys. According to the description, an attacker with physical access and Combine_Key_Parts permissions can perform a brute-force attack to create a 3DES...
