-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ESA-2012-020: EMC AutoStart Multiple Buffer Overflow Vulnerabilities. EMC Identifier: ESA-2012-020 CVE Identifier: CVE-2012-0409 Severity Rating: CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C) Affected products: EMC AutoStart 5.3.x EMC AutoStart 5.4.x Summary: EMC AutoStart contains multiple buffer overflow vulnerabilities which can be exploited to potentially cause a denial of service, or possibly, execute arbitrary code within the context of the affected application. Details: Security flaws were detected in AutoStart where malicious packets could be sent to agents to cause buffer overflow. Message could be modified to send values, which could then be used in performing arithmetic operations which in turn is used to allocate memory. Memory corruption resulting from such allocations can be exploited to gain remote code execution, cause crashes or repeated restarting of AutoStart agents affecting availability of agents. Resolution: The following EMC AutoStart product contains resolution to these issues: EMC AutoStart 5.4.3 EMC strongly recommends all customers upgrade at the earliest opportunity. Note: Customers on 5.3.x will have to first upgrade to 5.4.0 and then upgrade to 5.4.3 version. Link to Remedies: Registered EMC customers can download software from Powerlink.
