Red Hat has released a security advisory and updated packages to address the Adobe Reader and Acrobat sandbox bypass arbitrary code execution vulnerability.
Adobe Reader and Acrobat contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service condition or execute arbitrary code on a targeted system.
Adobe has confirmed the vulnerability and software updates are available.
Adobe Reader and Acrobat versions 11.0.01 and prior, 10.1.5 and prior, 9.5.3 and prior are vulnerable.
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 that 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 running the affected application. If the user holds elevated privileges, the attacker could cause a complete system compromise.
Technical details are unavailable.
