@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.

============================================================TOP VULNERABILITY THIS WEEK: A bug that spans nearly every known version of Android was announced last week, which allows for arbitrary modification of APK contents without compromising its digital signature. Public proof-of-concept already exists, and while rooted users with Cyanogenmod are already patched, users of mainstream, carrier-provided Android phones may be waiting for months before patches appear.

============================================================NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM
Title: Android "master key" bug allows tampering with APKs without
voiding crypto signatures
Description: A vulnerability that allows attackers to make arbitrary
modifications to the code of an Android APK without compromising its
digital signature was announced late last week in a blog post by Bluebox
Security, with a promise to release full details at the Black Hat
security conference later this month. Within days, public proof of
concept tools for implementing this attack emerged, as it became clear
that the bug centers around duplicate internal file names. While the
popular Cyanogenmod Android distribution has already patched their code
base, users of carrier-provided phones are looking at a wait that could
stretch out for months before an update arrives. As with most Android
security issues, users are urged to refrain from installing apps from
outside the official marketplace to lower their risk until a patch is
available.

Title: Microsoft Tuesday release covers 34 CVEs over 7 patches
Description: This week's patch release from Microsoft was a particularly
busy one, with six of the seven bulletins being marked as critical, and
a total of 34 CVEs fixed across those bulletins. While only one of the
issues were confirmed as being exploited in the wild prior to release -
CVE-2013-3660, which was being leveraged in targeted attacks for
escalation of privilege - several other issues had been publicly
disclosed, and exploits are likely to begin emerging in the coming days.

Title: Emergency responder systems vulnerable to multiple issues
Description: A slew of vulnerabilities were announced this week by
IOActive in Digital Alert Systems' DASDEC machines - used by emergency
responders throughout the United States - including a default SSH key
that allows for root logins, and a web application that allows full view
of logs without authentication. The vulnerabilities have already been
used to send fake national alerts about zombies; at this time, no patch
is available from the manufacturer.

RECENT VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE
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-2013-3660
Title: Microsoft Windows "win32k!EPATHOBJ::pprFlattenRec" Privilege
Escalation Vulnerability
Vendor: Microsoft
Description: The EPATHOBJ::pprFlattenRec function in win32k.sys in
Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista
SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8,
Windows Server 2012, and Windows RT does not properly initialize a
pointer for the next object in a certain list, which allows local users
to obtain write access to the PATHRECORD chain, and consequently gain
privileges, by triggering excessive consumption of paged memory and then
making many FlattenPath function calls.
CVSS v2 Base Score: 6.9 (AV:L/AC:M/Au:N/C:C/I:C/A:C)
ID: CVE-2013-2688
Title: QNX Phrelay Buffer Overflow Vulnerability
Vendor: QNX Software Systems Ltd
Description: Remote exploitation of a buffer overflow vulnerability in
QNX Software Systems Ltd.'s Phrelay could allow attackers to execute
arbitrary code on the targeted host.
CVSS v2 Base Score: 5.4 (AV:N/AC:H/Au:N/C:N/I:N/A:C)
ID: CVE-2013-2687
Title: QNX Multiple Products "bpe_decompress" Stack-based Buffer
Overflow Vulnerability
Vendor: QNX Software Systems Ltd
Description: Remote exploitation of a buffer overflow vulnerability in

CVSS v2 Base Score: 7.3 (AV:N/AC:L/Au:N/C:N/I:N/A:C)
ID: CVE-2013-2460 Title: Java Applet ProviderSkeleton Insecure Invoke Method Vendor: Oracle Description: Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 21 and earlier, and OpenJDK 7, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to Serviceability. NOTE: the previous information is from the June 2013 CPU. Oracle has not commented on claims from another vendor that this issue allows remote attackers to bypass the Java sandbox via vectors related to "insufficient access checks" in the tracing component. CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
ID: CVE-2013-2551
Title: Microsoft Internet Explorer COALineDashStyleArray Integer
Overflow (MS13-009)
Vendor: Microsoft
Description: Use-after-free vulnerability in Microsoft Internet Explorer
6 through 10 allows remote attackers to execute arbitrary code via a
crafted web site that triggers access to a deleted object, as
demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2013,
aka "Internet Explorer Use After Free Vulnerability," a different
vulnerability than CVE-2013-1308 and CVE-2013-1309.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
