From remote

System access

This covers vulnerabilities where malicious people are able to gain system access and execute arbitrary code with the privileges of a local user.

Exposure of sensitive information

Vulnerabilities where documents or credentials are leaked or can be revealed either locally or from remote.

Security Bypass

This covers vulnerabilities or security issues where malicious users or people can bypass certain security mechanisms of the application.

The actual impact varies significantly depending on the design and purpose of the affected application.

Multiple vulnerabilities have been reported in Adobe Flash Player, which can be exploited by malicious people to disclose sensitive information, bypass certain security restrictions, or compromise a user's system.

1) An unspecified error can be exploited to execute arbitrary code.

NOTE: The vulnerability is currently being actively exploited.

2) An input validation error can be exploited to bypass cross-domain policy file restrictions when certain server encodings are being used.

3) An unspecified error in the "Flash10h.ocx" ActiveX control can be exploited to corrupt memory and potentially execute arbitrary code.

4) An unspecified error can be exploited to disclose potentially sensitive information.

Successful exploitation of this vulnerability is limited to the Macintosh platform and the Safari browser.

5) An unspecified error can be exploited to cause a crash and potentially execute arbitrary code.

6) Multiple unspecified errors can be exploited to corrupt memory and potentially execute arbitrary code.

7) An error due to loading libraries in an insecure manner can be exploited to load arbitrary libraries by tricking a user into e.g. opening a file located on a remote WebDAV or SMB share.

Successful exploitation of this vulnerability may allow execution of arbitrary code.
