@RISK provides a reliable weekly summary of (1) newly discovered attack vectors, (2) vulnerabilities with active new exploits, (3) insightful explanations of how recent attacks worked, and other valuable data
A key purpose of the @RISK is to provide the data that will ensure that the 20 Critical Controls (the US and UK benchmark for effective protection of networked systems) continue to be the most effective defenses for all known attack vectors. But since it is also valuable for security practitioners, SANS is making it available to the 145,000 security practitioners who have completed SANS security training and others at their organizations who hope to stay current with the offensive methods in use.

COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM.
This is a list of recent vulnerabilities for which exploits are available. System administrators can use this list to help in prioritization of their remediation activities. The Qualys Vulnerability Research Team compiles this information based on various exploit frameworks, exploit databases, exploit kits and monitoring of internet activity.
ID: CVE-2015-0313
Title: Adobe Flash Player Use-After-Free Vulnerability
Vendor: Adobe
Description: Use-after-free vulnerability in Adobe Flash Player before
13.0.0.269 and 14.x through 16.x before 16.0.0.305 on Windows and OS X
and before 11.2.202.442 on Linux allows remote attackers to execute
arbitrary code via unspecified vectors, as exploited in the wild in
February 2015, a different vulnerability than CVE-2015-0315,
CVE-2015-0320, and CVE-2015-0322.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2015-0318
Title: Adobe Flash Player Memory Corruption Vulnerability
Vendor: Adobe
Description: Adobe Flash Player before 13.0.0.269 and 14.x through 16.x
before 16.0.0.305 on Windows and OS X and before 11.2.202.442 on Linux
allows attackers to execute arbitrary code or cause a denial of service
(memory corruption) via unspecified vectors, a different vulnerability
than CVE-2015-0314, CVE-2015-0316, CVE-2015-0321, CVE-2015-0329, and
CVE-2015-0330.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2014-4114
Title: Exim GHOST (glibc gethostbyname) Buffer Overflow
Vendor: Exim.org
Description: Heap-based buffer overflow in the
__nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions
before 2.18, allows context-dependent attackers to execute arbitrary
code via vectors related to the (1) gethostbyname or (2) gethostbyname2
function, aka "GHOST."
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2014-4114
Title: Microsoft Windows OLE - Remote Code Execution "Sandworm" Exploit
(MS14-060)
Vendor: Microsoft
Description: Microsoft Windows Vista SP2, Windows Server 2008 SP2 and
R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold
and R2, and Windows RT Gold and 8.1 allow remote attackers to execute
arbitrary code via a crafted OLE object in an Office document, as
exploited in the wild with a "Sandworm" attack in June through October
2014, aka "Windows OLE Remote Code Execution Vulnerability."
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
ID: CVE-2014-7169
Title: Multiple Vendor Bash Remote Code Execution Vulnerability
Vendor: Multiple Vendors
Description: GNU Bash through 4.3 bash43-025 processes trailing strings
after certain malformed function definitions in the values of
environment variables, which allows remote attackers to write to files
or possibly have unknown other impact via a crafted environment, as
demonstrated by vectors involving the ForceCommand feature in OpenSSH
sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server,
scripts executed by unspecified DHCP clients, and other situations in
which setting the environment occurs across a privilege boundary from
Bash execution. NOTE: this vulnerability exists because of an incomplete
fix for CVE-2014-6271.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2014-6271
Title: Multiple Vendor Bash Remote Code Execution Vulnerability
Vendor: Multiple Vendors
Description: GNU Bash through 4.3 processes trailing strings after
function definitions in the values of environment variables, which
allows remote attackers to execute arbitrary code via a crafted
environment, as demonstrated by vectors involving the ForceCommand
feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache
HTTP Server, scripts executed by unspecified DHCP clients, and other
situations in which setting the environment occurs across a privilege
boundary from Bash execution, aka "ShellShock." NOTE: the original fix
for this issue was incorrect; CVE-2014-7169 has been assigned to cover
the vulnerability that is still present after the incorrect fix.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
