@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.

NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP VULNERABILITY RESEARCH TEAM
Title: ICU Project ICU4C library contains multiple overflow vulnerabilities
Description: ICU Project ICU4C library, versions 52 through 54, contains
a heap-based buffer overflow and an integer overflow vulnerability. An
attacker may be able to provide input that triggers one or both overflow
vulnerabilities, leading to denial of service and the possibility of
code execution. These issues have been addressed in ICU4C version 55.1.
Developers are encouraged to update applications that make use of
affected versions of ICU4C. Users of affected products should check with
product vendors for updates that utilize a patched version of ICU4C.
Reference: http://www.kb.cert.org/vuls/id/602540
Title: Hospira LifeCare PCA3 Drug Infusion Pumps Contain Multiple Remotely Exploitable Vulnerabilities
Description: The Hospira LifeCare PCA3 Drug Infusion Pump has been found
to contain multiple remotely exploitable security vulnerabilities.
Vulnerabilities such as the ability for an attacker to get an
unauthenticated remote root shell, hardcoded local accounts with
administrative privileges, storage of wireless keys in clear text, and
the use of additional software packages that have had security patches
released since the device has shipped are some of the vulnerabilities
found within the device. The U.S. Dept. of Homeland Security has issued
an advisory, indicating that the vendor is currently working to patch
these vulnerabilities.

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-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

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)
