CVE-2009-4212

Status Candidate

Overview

Multiple integer underflows in the (1) AES and (2) RC4 decryption functionality in the crypto library in MIT Kerberos 5 (aka krb5) 1.3 through 1.6.3, and 1.7 before 1.7.1, allow remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code by providing ciphertext with a length that is too short to be valid.

Debian Linux Security Advisory 1969-1
Posted Jan 14, 2010
Authored by Debian | Site debian.org

Debian Linux Security Advisory 1969-1 - It was discovered that krb5, a system for authenticating users and services on a network, is prone to integer underflow in the AES and RC4 decryption operations of the crypto library. A remote attacker can cause crashes, heap corruption, or, under extraordinarily unlikely conditions, arbitrary code execution.

MIT krb5 Security Advisory 2009-004 - Integer underflow bugs in the AES and RC4 decryption operations of the crypto library of the MIT Kerberos software can cause crashes, heap corruption, or, under extraordinarily unlikely conditions, arbitrary code execution. Only releases krb5-1.3 and later are vulnerable, as earlier releases did not contain the functionality implemented by the vulnerable code.

Ubuntu Security Notice 881-1 - It was discovered that Kerberos did not correctly handle invalid AES blocks. An unauthenticated remote attacker could send specially crafted traffic that would crash the KDC service, leading to a denial of service, or possibly execute arbitrary code with root privileges.
