Adobe out-of-band security updates address 82 flaws in 3 products

Adobe has released out-of-band security updates to address a total of 82 security vulnerabilities that affect three products of the company.

On Tuesday, Adobe released out-of-band security updates to address 82 flaws in Acrobat and Reader, Experience Manager, Experience Manager Forms, and Download Manager.

Out of 82 security flaws, 45 vulnerabilities affecting Adobe Acrobat and Reader have been rated critical. The exploitation of the flaws could lead to arbitrary code execution in the context of the current user.

The company also addressed 23 important-rated out-of-bounds read and cross-site scripting issues that could lead to information disclosure.

26 vulnerabilities in Adobe Acrobat and Reader reside due to use-after-free, 6 due to out-of-bounds write, 4 are type confusion bugs, 4 are untrusted pointer dereference, 3 are heap overflow bugs, one a buffer overrun and one a race condition flaw.

A majority of critical-rated vulnerabilities (i.e., 26) in Adobe Acrobat and Reader reside due to use-after-free, 6 due to out-of-bounds write, 4 are type confusion bugs, 4 due to untrusted pointer dereference, 3 are heap overflow bugs, one buffer overrun and one race condition issue.

Adobe fixed a privilege escalation flaw in Download Manager for Windows that is caused by insecure file permissions.

Adobe also addressed a dozen flaws in the Experience Manager marketing solution. An attacker could exploit the vulnerabilities to gain unauthorized access to an organization’s Experience Manager environment.

The company also fixed a XSS flaw in the Experience Manager Forms that lead to the disclosure of sensitive information.

The good news is that Adobe is not aware of any attacks exploiting the vulnerabilities in the wild.
