Link    : https://wiki.archlinux.org/title/CVE

Summary
======
The package flashplugin before version 11.2.202.440-1 is vulnerable to
multiple issues including remote code execution, denial of service,
keylogging and memory leaks.

Resolution
=========
Upgrade to 11.2.202.440-1.

# pacman -Syu "flashplugin>=11.2.202.440-1"

The problems have been fixed upstream in version 11.2.202.440.

Workaround
=========
None.

Description
==========
- CVE-2015-0311 (remote code execution)

Unspecified vulnerability allows remote attackers to execute arbitrary
code via unknown vectors, as exploited in the wild in January 2015.

- CVE-2015-0309 (remote code execution)

Heap-based buffer overflow allows attackers to execute arbitrary code
via unspecified vectors, a different vulnerability than CVE-2015-0304.

- CVE-2015-0308 (remote code execution)

Use-after-free vulnerability allows attackers to execute arbitrary code
via unspecified vectors.

- CVE-2015-0307 (memory leaks, denial of service)

A vulnerability allows remote attackers to obtain sensitive information
from process memory or cause a denial of service (out-of-bounds read)
via unspecified vectors.

- CVE-2015-0306 (remote code execution, denial of service)

A vulnerability allows attackers to execute arbitrary code or cause a
denial of service (memory corruption) via unspecified vectors, a
different vulnerability than CVE-2015-0303.

- CVE-2015-0305 (remote code execution)

A vulnerability allows attackers to execute arbitrary code by leveraging
an unspecified "type confusion".

- CVE-2015-0304 (remote code execution)

Heap-based buffer overflow allows attackers to execute arbitrary code
via unspecified vectors, a different vulnerability than CVE-2015-0309.

- CVE-2015-0303 (remote code execution, denial of service)

A vulnerability allows attackers to execute arbitrary code or cause a
denial of service (memory corruption) via unspecified vectors, a
different vulnerability than CVE-2015-0306.

- CVE-2015-0302 (keylogging)

A vulnerability allows attackers to obtain sensitive keystroke
information via unspecified vectors.

- CVE-2015-0301 (file validation)

The flashplugin does not properly validate files, which has unspecified
impact and attack vectors.


Impact
=====
A remote attacker is able to perform remote code execution, keylogging,
denial of service and resource consumption through memory leaks.
