Adobe has released security updates for Acrobat, Reader, and Lightroom that fix a total of twenty-six vulnerabilities in the three programs. Of the vulnerabilities, 11 are classified as ‘Critical’ because they allow attackers to bypass security features or perform remote code execution on vulnerable computers. Users should upgrade to the latest versions of Acrobat and Reader to resolve these vulnerabilities. A DLL hijacking vulnerability is fixed in Lightroom Classic 9.3 to fix a DLL vulnerability that would allow an attacker to execute commands with elevated privileges.
