Name of the Vulnerable Software and Affected Versions Adobe Flash Player versions 27.0.0.183 and earlier

Description The issue is caused by an integer overflow when creating a bitmap image, leading to an out-of-bounds access. This can allow a remote attacker to execute arbitrary code. The vulnerability occurs due to a computation that reads data past the end of the target buffer. A successful attack can lead to sensitive data exposure.

Recommendations For Adobe Flash Player versions 27.0.0.183 and earlier, update to a version that contains a fix for this issue to prevent remote code execution. As a temporary workaround, consider restricting access to bitmap image creation functions until a patch is available.
