Unauthenticated remote attackers that can connect to the "CloudMe Sync" client application listening on port 8888, can send a malicious payload causing

a Buffer Overflow condition. This will result in an attacker controlling the programs execution flow and allowing arbitrary code execution on the victims PC.
Spectre breaks the isolation between different applications. It allows an attacker to trick error-free programs, which follow best practices, into leaking their secrets. In fact, the safety checks of said best practices actually increase the attack surface and may make applications more susceptible to Spectre
This module exploits a race condition vulnerability in the Linux Kernel via MAP_PRIVATE COW.



The bug relies in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.



This update improves the post-escalation execution.
The specific flaw exists within the processing of ARF files. While opening an ARF file, WebEx Network Recording Player loads a DLL from an unqualified path. An attacker can leverage this vulnerability to execute code under the context of the current process.
