CVE-2006-2940

TITLE

OpenSSL SSLv2 client code fails to properly check for NULL

DESCRIPTION

OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows attackers to cause a denial of service (CPU consumption) via parasitic public keys with large (1) "public exponent" or (2) "public modulus" values in X.509 certificates that require extra time to process when using RSA signature verification. A flaw in the OpenSSL library could allow a remote attacker to cause a denial of service on an affected application. Multiple RSA implementations fail to properly handle RSA signatures. This vulnerability may allow an attacker to forge RSA signatures. OpenSSL is prone to a denial-of-service vulnerability because it fails to validate the lengths of public keys being used. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 - ------------------------------------------------------------------- ~ VMware Security Advisory Advisory ID: VMSA-2008-0005 Synopsis: Updated VMware Workstation, VMware Player, VMware ~ Server, VMware ACE, and VMware Fusion resolve ~ critical security issues Issue date: 2008-03-17 Updated on: 2008-03-17 (initial release of advisory) CVE numbers: CVE-2008-0923 CVE-2008-0923 CVE-2008-1361 ~ CVE-2008-1362 CVE-2007-5269 CVE-2006-2940 ~ CVE-2006-2937 CVE-2006-4343 CVE-2006-4339 ~ CVE-2007-5618 CVE-2008-1364 CVE-2008-1363 ~ CVE-2008-1340 - ------------------------------------------------------------------- 1. Summary: ~ Several critical security vulnerabilities have been addressed ~ in the newest releases of VMware's hosted product line. 2. Relevant releases: ~ VMware Workstation 6.0.2 and earlier ~ VMware Workstation 5.5.4 and earlier ~ VMware Player 2.0.2 and earlier ~ VMware Player 1.0.4 and earlier ~ VMware ACE 2.0.2 and earlier ~ VMware ACE 1.0.2 and earlier ~ VMware Server 1.0.4 and earlier ~ VMware Fusion 1.1 and earlier 3. Problem description: ~ a. Host to guest shared folder (HGFS) traversal vulnerability ~ On Windows hosts, if you have configured a VMware host to guest ~ shared folder (HGFS), it is possible for a program running in the ~ guest to gain access to the host's file system and create or modify ~ executable files in sensitive locations. NOTE: VMware Server is not affected because it doesn't use host to ~ guest shared folders. No versions of ESX Server, including ~ ESX Server 3i, are affected by this vulnerability. Because ~ ESX Server is based on a bare-metal hypervisor architecture ~ and not a hosted architecture, and it doesn't include any ~ shared folder abilities. Fusion and Linux based hosted ~ products are unaffected. ~ VMware would like to thank CORE Security Technologies for ~ working with us on this issue.
