Red Hat has released a security advisory and updated packages to address the Adobe Reader and Acrobat sandbox escape arbitrary code execution vulnerability.
Adobe Reader and Acrobat contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or execute arbitrary code.
Adobe has confirmed the vulnerability; however, software updates are unavailable.
The following Adobe products are affected:
Adobe Reader versions 11.0.01 and prior, 10.1.5 and prior, and 9.5.3 and prior
Adobe Acrobat versions 11.0.01 and prior, 10.1.5 and prior, and 9.5.3 and prior
To exploit the vulnerability, the attacker may provide a link that directs a user to a malicious file and use misleading language or instructions to persuade the user to follow the provided link and open the malicious file.
The CVSS score indicates functional exploit code exists, and third-party reports indicate the vulnerability is being actively exploited; however, the code is not known to be publicly available.
An unauthenticated, remote attacker could exploit the vulnerability to cause a DoS condition or execute arbitrary code in the security context of the user who is running the affected application. If the user holds elevated privileges, the attacker could completely compromise the targeted system.
Technical details are unavailable.
Administrators may consider enabling Protected View in the registry and propagating that setting via Group Policy Object (GPO) to help protect Windows users.
Administrators are advised to contact the vendor regarding future updates and releases.
Users are advised not to open e-mail messages from suspicious or unrecognized sources. If users cannot verify that links or attachments included in e-mail messages are safe, they are advised not to open them.
Administrators are advised to monitor affected systems.
