Vulnerability Information .NET Framework Serialization Vulnerability - CVE-2012-0160 A remote code execution vulnerability exists in the Microsoft .NET Framework due to the improper serialization of untrusted input. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-0160. .NET Framework Serialization Vulnerability - CVE-2012-0161 A remote code execution vulnerability exists in the Microsoft .NET Framework due to the improper serialization of untrusted input through partially trusted assemblies. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-0161. - --------------------------END INCLUDED TEXT-------------------- You have received this e-mail bulletin as a result of your organisation's registration with AusCERT.
