Detailsinfo

A vulnerability, which was classified as very critical, was found in Rockwell RSLinx Enterprise Cpr9. This affects some unknown processing in the library Logger.dll of the file LogReceiver.exe. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in LogReceiver.exe in Rockwell Automation RSLinx Enterprise CPR9, CPR9-SR1, CPR9-SR2, CPR9-SR3, CPR9-SR4, CPR9-SR5, CPR9-SR5.1, and CPR9-SR6 allows remote attackers to cause a denial of service (daemon crash) or possibly execute arbitrary code via a UDP packet with a certain integer length value that is (1) too large or (2) too small, leading to improper handling by Logger.dll.

The weakness was presented 04/18/2013 by Carsten Eiram (Website). The advisory is shared at ics-cert.us-cert.gov. This vulnerability is uniquely identified as CVE-2012-4715 since 08/28/2012.
