Security Bulletin: IBM DataPower Gateway vulnerable to data truncation and DoS in Kerberos (CVE-2024-37370 & CVE-2024-37371)

Summary Kerberos is used by IBM DataPower Gateway as an optional authentication mechanism. Vulnerability Details CVEID:CVE-2024-37370 DESCRIPTION: MIT Kerberos 5 aka krb5 could allow a remote attacker to bypass security restrictions, caused by improper access control. By sending a specially craft...

Fedora 40 : dovecot (2024-e23e8a3f1e)

The remote Fedora 40 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-e23e8a3f1e advisory. - CVE-2024-23184: A large number of address headers in email resulted in excessive CPU usage. - CVE-2024-23185: Abnormally large email headers are n...

CVE-2024-1544 ECDSA nonce bias caused by truncation

Generating the ECDSA nonce k samples a random number r and then truncates this randomness with a modular reduction mod n where n is the order of the elliptic curve. Meaning k = r mod n. The division used during the reduction estimates a factor qe by dividing the upper two digits a digit having e....

CVE-2024-1544

CVE-2024-1544 describes a bias in the ECDSA nonce generation when k is obtained as r mod n, where a control-flow dependent reduction leaks MSB bias in k. The issue can enable lattice-reduction based reconstruction of k for certain curves (e.g., SECP160R1 with about 15 bits of bias). The connected...

krb5: GSS message token handling
