Detailsinfo

A vulnerability, which was classified as very critical, has been found in Samba up to 3.6.x (File Transfer Software). This issue affects the function ReportEventW. The manipulation with an unknown input leads to a numeric error vulnerability. Using CWE to declare the problem leads to CWE-189. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

The RPC code generator in Samba 3.x before 3.4.16, 3.5.x before 3.5.14, and 3.6.x before 3.6.4 does not implement validation of an array length in a manner consistent with validation of array memory allocation, which allows remote attackers to execute arbitrary code via a crafted RPC call.
