http://lists.vmware.com/pipermail/security-announce/2010/000111.html
QUOTE: It's an update for VMware ESX 4.1 without patch ESX410-201011001. Here's the problem description right off of their website: Service Console OS update for COS kernel package. This patch updates the Service Console kernel to fix a stack pointer underflow issue in the 32-bit compatibility layer. Exploitation of this issue could allow a local user to gain additional privileges.
