Quote:Adobe is warning customers of a critical zero-day bug actively exploited in the wild that affects its ubiquitous Adobe Acrobat PDF reader software. A patch is available, as part of the company’s Tuesday roundup of 43 fixes for 12 of its products, including Adobe Creative Cloud Desktop Application, Illustrator, InDesign, and Magento.
 
According to Adobe, the zero-day vulnerability, which is tracked as CVE-2021-28550, “has been exploited in the wild in limited attacks targeting Adobe Reader users on Windows.”
 
Windows users of Adobe Reader may be the only ones currently targeted. However, the bug affects eight versions of the software, including those running on Windows and macOS systems. Versions include:

• Windows Acrobat DC & Reader DC (versions 2021.001.20150 and earlier)
  
• macOS Acrobat DC & Reader DC (versions 2021.001.20149 and earlier)
  
• Windows & macOS Acrobat 2020 & Acrobat Reader 2020 (2020.001.30020 and earlier versions)
  
• Windows & macOS Acrobat 2017 & Acrobat Reader 2017 (2017.011.30194  and earlier versions)
  

Adobe did not release technical specifics regarding the zero-day vulnerability. Typically, those details become available after users have had an opportunity to apply the fix. “Users can update their product installations manually by choosing Help > Check for Updates,” Adobe wrote in its May security bulletin, posted Tuesday.
