Descriptions

VMware Horizon 6 (6.x.x before 6.2.7), Horizon 7 (7.x.x before 7.5.1), and Horizon Client (4.x.x and prior before 4.8.1) contain an out-of-bounds read vulnerability in the Message Framework library. Successfully exploiting this issue may allow a less-privileged user to leak information from a privileged process running on a system where Horizon Connection Server, Horizon Agent or Horizon Client are installed. Note: This issue doesn't apply to Horizon 6, 7 Agents installed on Linux systems or Horizon Clients installed on non-Windows systems.

VMware Horizon 6 (6.x.x en versiones anteriores a la 6.2.7), Horizon 7 (7.x.x en versiones anteriores a la 7.5.1) y Horizon Client (4.x.x en versiones anteriores a la 4.8.1) contiene una vulnerabilidad de lectura fuera de límites en la librería Message Framework. Su explotación con éxito podría permitir que un usuario con menos privilegios filtre información desde un proceso privilegiado que se ejecuta en un sistema donde estén instalados Horizon Connection Server, Horizon Agent o Horizon Client. Nota: este problema no aplica a los agentes de Horizon 6 y 7 instalados en los sistemas Linux o a los clientes de Horizon instalados en sistemas que no son Windows.

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of VMware Horizon Client. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within messages passed to the wswc_sharedMem_shared shared memory. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of SYSTEM.
