Adobe Patches Critical RoboHelp Server Security Flaw
Software maker Adobe on Tuesday released patches to cover at least four documented security defects that expose users to malicious hacker attacks.
The most serious of the flaw was addressed in RoboHelp Server and is rated “critical” because it exposes corporate environments to arbitrary code execution attacks.
Adobe warned that the vulnerability — CVE-2021-39858 — affects RoboHelp Server RHS2020.0.1 and earlier versions on the Microsoft Windows platform.
The company said it was unaware of any exploits in the wild targeting this flaw.
Separately, Adobe released security updates for its widely deployed Creative Cloud Desktop Application, confirming a denial of service flaw (CVE-2021-43017) exists in Version 5.5 and earlier versions for Apple’s macOS platform.
The company also provided security patches for a pair of vulnerabilities in the Adobe InCopy product.
These two vulnerabilities — CVE-2021-43015 and CVE-2021-43016 — can be exploited to launch arbitrary code execution and application denial-of-service attacks, Adobe said in a bulletin posted Tuesday.
The Adobe InCopy flaws affect versions 16.4 and earlier on both Windows and macOS platforms.
