Adobe Flash Player Dereferenced Pointer Vulnerability
Adobe · Flash Player
Summary
Adobe Flash Player (and the related Adobe AIR and AIR SDK products) contains a dereferenced pointer flaw, classified as an out-of-bounds memory and use-after-free issue, in the affected builds of Flash Player for Windows, OS X and Linux. An attacker over the network can execute arbitrary code or crash the software by exploiting unspecified vectors, which requires a user to take an action such as opening crafted content.
Official description · NVD
Adobe Flash Player before 13.0.0.258 and 14.x and 15.x before 15.0.0.239 on Windows and OS X and before 11.2.202.424 on Linux, Adobe AIR before 15.0.0.293, Adobe AIR SDK before 15.0.0.302, and Adobe AIR SDK & Compiler before 15.0.0.302 allow attackers to execute arbitrary code or cause a denial of service (invalid pointer dereference) via unspecified vectors.
