The last Patch Tuesday of 2019 is finally here.

Adobe today released updates for four of its widely used software—including Adobe Acrobat and Reader, Photoshop CC, ColdFusion, and Brackets—to patch a total of 25 new security vulnerabilities.

Seventeen of these flaws have been rated as critical in severity, with most of them carrying high priority patches, indicating that the vulnerabilities are more likely to be used in real-world attacks, but there are currently no known exploits in the wild.

The software update for Adobe Acrobat and Reader for Windows and macOS operating systems addresses a total of 21 security vulnerabilities, 14 of which are critical, and rest are important in severity.

Upon successful exploitation, all critical vulnerabilities in Adobe Acrobat and Reader software lead to arbitrary code execution attacks, allowing attackers to take complete control of targeted systems.

Adobe Photoshop CC for Windows and macOS contains patches for two critical arbitrary code execution vulnerabilities that were discovered and reported to the company by Honggang Ren of Fortinet's FortiGuard Labs.

The last two flaws the company patched this month affect Brackets, a source code editor, and ColdFusion, a commercial rapid web application development platform by Adobe.

The software update for Brackets addresses a critical code execution flaw, which was disclosed by Tavis Ormandy of Google Project Zero.

Adobe ColdFusion update comes with a security patch for an important privilege escalation bug, which occurs due to insecure inherited permissions of the default installation directory.

The company has released updated versions for all four vulnerable software for each impacted platform that users should install immediately to protect their systems and businesses from cyber-attacks.

If your system hasn't yet detected the availability of the new update automatically, you should manually install the update by choosing "Help → Check for Updates" in your Adobe software.
