Technical details

Citrix Provisioning Services (PVS) versions prior to 7.12 are vulnerable to a memory corruption issue classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer). The vulnerability allows a remote, unauthenticated attacker to overwrite a function pointer within the application's memory space. By sending specially crafted network traffic to the PVS server, an attacker can redirect the flow of execution to arbitrary code. This results in full system compromise with the privileges of the Provisioning Services process. The issue is resolved in Citrix Provisioning Services version 7.12.

Affected products

Citrix Provisioning Services 7.0, 7.1, 7.6, 7.7, 7.8, 7.9, 7.11
