TOP VULNERABILITY THIS WEEK: A pair of recent Adobe patches have closed

off vulnerabilities that were being exploited in the wild as targeted
0-days, with payloads that used a new technique to evade
operating-system level mitigations of ASLR and DEP.


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: Recently Patched Flash Vulnerabilities Actively Exploited In The Wild
Description: A pair of Adobe Flash vulnerabilities were patched last
week, closing holes that were being exploited in the wild at the time
of the patches. The attack payloads included creative new ways around
common operating system level mitigations such as ASLR and DEP, making
them particularly problematic for defenders. While attacks appear to
have been limited in scope, particularly compared to last month’s Java
0-day issues, high value targets in particular are urged to patch
immediately.

Title: Huge Microsoft Tuesday Includes Low-Level TCP/IP DoS
Description: Microsoft this week issued a huge set of patches, closing
off 57 distinct CVEs in a total of 11 security notices. While many of
these vulnerabilities will likely prove difficult to exploit in the
wild, the VML memory corruption attack (CVE-2013-0030) is already being
used for information disclosure in targeted attacks. Most likely to
wreak havoc is the TCP/IP “Finshake” denial of service (CVE-2013-0075)

stack” - which requires minimal attacker bandwidth and applies to any
Microsoft operating system, regardless of which services are made
available to the Internet. Administrators are urged to test and patch
their systems as rapidly as feasible, given the size of this release.

Title: Microsoft, Symantec Take Down Bamital Botnet
Description: Continuing its winning streak in US federal courts,
Microsoft’s Digital Crimes Unit - in conjunction with security provider
Symantec - executed a takedown of the massive Bamital botnet, which was
responsible for major advertising fraud activities across the globe and
distribution of copious amounts of peripheral malware. Infected users
are now getting messages with cleanup instructions; unlike previous
takedowns, such as DNSChanger, currently-infected systems are, however,
can still be used on the Internet generally.

Title: Security Firm Bit9 Compromised
Description: After failing to install its own application whitelisting
product on all of its internal systems, security firm Bit9 revealed last
week that it had been compromised, and that intruders had used its
digital signing certificates to push malicious applications as if they
were trusted code. While the firm has responded promptly and is working
with all potentially impacted parties on cleanup, the compromise
reiterates the necessity of following internal security policy in all
circumstances, not just those where doing so is easy. Note that users
of Sourcefire’s FireAMP technology are protected from these malicious
binaries through certificate revocation technology.

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-2013-0422
Title: Oracle Java SE Security Bypass Vulnerability
Vendor: Oracle
Description: Multiple vulnerabilities in Oracle Java 7 before Update 11
allow remote attackers to execute arbitrary code by (1) using the public
getMBeanInstantiator method in the JmxMBeanServer class to obtain a
reference to a private MBeanInstantiator object, then retrieving
arbitrary Class references using the findClass method, and (2) using the
Reflection API with recursion in a way that bypasses a security check
by the java.lang.invoke.MethodHandles.Lookup.checkSecurityManager method
due to the inability of the sun.reflect.Reflection.getCallerClass method
to skip frames related to the new reflection API, as exploited in the
wild in January 2013, as demonstrated by Blackhole and Nuclear Pack, and
a different vulnerability than CVE-2012-4681 and CVE-2012-3174. NOTE:
some parties have mapped the recursive Reflection API issue to
CVE-2012-3174, but CVE-2012-3174 is for a different vulnerability whose
details are not public as of 20130114. CVE-2013-0422 covers both the
JMX/MBean and Reflection API issues. NOTE: it was originally reported
that Java 6 was also vulnerable, but the reporter has retracted this
claim, stating that Java 6 is not exploitable because the relevant code
is called in a way that does not bypass security checks. NOTE: as of
20130114, a reliable third party has claimed that the
findClass/MBeanInstantiator vector was not fixed in Oracle Java 7 Update

  1. If there is still a vulnerable condition, then a separate CVE
    identifier might be created for the unfixed issue.
    CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2012-5088
Title: Java Applet Method Handle Remote Code Execution
Vendor: Oracle
Description: Unspecified vulnerability in the Java Runtime Environment
(JRE) component in Oracle Java SE 7 Update 7 and earlier allows remote
attackers to affect confidentiality, integrity, and availability via
unknown vectors related to Libraries.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2012-5076
Title: Java Applet AverageRangeStatisticImpl Remote Code Execution
Vendor: Oracle
Description: Unspecified vulnerability in the Java Runtime Environment
(JRE) component in Oracle Java SE 7 Update 7 and earlier allows remote
attackers to affect confidentiality, integrity, and availability,
related to JAX-WS.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2012-5958
Title: Portable UPnP SDK unique_service_name() Remote Code Execution
Vendor: libupnp.org
Description: Stack-based buffer overflow in the unique_service_name
function in ssdp/ssdp_server.c in the SSDP parser in the portable SDK
for UPnP Devices (aka libupnp, formerly the Intel SDK for UPnP devices)
before 1.6.18 allows remote attackers to execute arbitrary code via a
UDP packet with a crafted string that is not properly handled after a
certain pointer subtraction.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2012-3569
Title: VMWare OVF Tools Format String Vulnerability
Vendor: VMWare
Description: Format string vulnerability in VMware OVF Tool 2.1 on
Windows, as used in VMware Workstation 8.x before 8.0.5, VMware Player
4.x before 4.0.5, and other products, allows user-assisted remote
attackers to execute arbitrary code via a crafted OVF file.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
