Multiple vulnerabilities have been identified in various VMware products, which could be exploited by attackers to bypass security restrictions, cause a denial of service or potentially execute arbitrary code.
The first issue is caused by an error in the virtual machine process (VMX) that reads state information from an incorrect memory location when returning from a sleep state (S2) to the run state (S0), which could be exploited by attackers to create a denial of service condition.
The second vulnerability is caused by an error in the virtual machine process (VMX) when storing configuration information in VMware system files, which could be exploited by attackers to cause a denial of service on the guest operating system.
The third issue is caused by an error when handling certain general protection faults (GPFs) in Windows guest operating systems, which could be exploited by attackers to crash a Windows virtual machine or potentially execute arbitrary code.
The fourth vulnerability is caused by a memory corruption error when debugging local programs executed on 64-bit Windows systems, which could be exploited to cause a denial of service or potentially execute arbitrary code.
The fifth issue is caused by an input validation error in the "Shared Folders" feature, which could be exploited by attackers to read or write arbitrary content on the host system.
The sixth vulnerability is caused by an unspecified error which could allow a malicious user to make plaintext additions to the encrypted preferences file by overwriting the file while VMware Player is running.
