CVE-2017-11213: Adobe Flash Player

Critical severity, CVSS 9.8. EPSS: 6.5% chance of exploitation in the next 30 days.

An issue was discovered in Adobe Flash Player 27.0.0.183 and earlier versions. This vulnerability occurs as a result of a computation that reads data that is past the end of the target buffer due to an integer overflow; the computation is part of the abstraction that creates an arbitrarily sized transparent or opaque bitmap image. The use of an invalid (out-of-range) pointer offset during access of internal data structure fields causes the vulnerability. A successful attack can lead to sensitive data exposure.

Affected products

• Adobe Flash Player: up to and including 27.0.0.183
• Red Hat Enterprise Linux Desktop: version 6.0 only
• Red Hat Enterprise Linux Server: version 6.0 only
• Red Hat Enterprise Linux Workstation: version 6.0 only
