TOP VULNERABILITY THIS WEEK: Denial of service in Wordpress 3.5.1


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE SOURCEFIRE VULNERABILITY RESEARCH TEAM

Title: JavaDoc frame injection vulnerability
Description: Javadoc is a tool that generates frames for online
documentation webapps such as
http://docs.oracle.com/javase/7/docs/api/. However there is a
vulnerability in how javadoc interprets user supplied frames and by
using the a variation, the frame will use the user supplied frame. This
can be put into a webpage and the user will click it, thinking he is
going to the docs.oracle site, but the frame will incorporate the
malicious redirection. Oracle has just released its security update for
June 2013 - a release that comprises of 40 security updates, with 37 of
them addressing vulnerabilities that lead to malware execution. Among
the updates is one that fixes the vulnerability found in Javadoc.

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-2013-2551
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)

ID: CVE-2012-1533
Title: Java Web Start Double Quote Injection Remote Code Execution
Vendor: Oracle
Description: Unspecified vulnerability in the Java Runtime Environment
(JRE) component in Oracle Java SE 7 Update 7 and earlier, and 6 Update
35 and earlier, allows remote attackers to affect confidentiality,
integrity, and availability via unknown vectors related to Deployment.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2013-1311
Title: Microsoft Internet Explorer textNode Use-After-Free
Vendor: Microsoft
Description: Use-after-free vulnerability in Microsoft Internet Explorer
8 allows remote attackers to execute arbitrary code via a crafted web
site that triggers access to a deleted object, aka “Internet Explorer
Use After Free Vulnerability.”
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

ID: CVE-2013-1559
Title: Oracle WebCenter Content CheckOutAndOpen.dll ActiveX Remote Code
Execution
Vendor: Oracle
Description: Unspecified vulnerability in the Oracle WebCenter Content
component in Oracle Fusion Middleware 10.1.3.5.1 and 11.1.1.6.0 allows
remote authenticated users to affect availability via unknown vectors
related to Content Server.
CVSS v2 Base Score: 4.0 (AV:N/AC:L/Au:S/C:N/I:N/A:P)

ID: CVE-2013-2423
Title: Java Applet Reflection Type Confusion Remote Code Execution
Vendor: Oracle
Description: Unspecified vulnerability in the Java Runtime Environment
(JRE) component in Oracle Java SE 7 Update 17 and earlier, and OpenJDK
7, allows remote attackers to affect integrity via unknown vectors
related to HotSpot. NOTE: the previous information is from the April
2013 CPU. Oracle has not commented on claims from the original
researcher that this vulnerability allows remote attackers to bypass
permission checks by the MethodHandles method and modify arbitrary
public final fields using reflection and type confusion, as demonstrated
using integer and double fields to disable the security manager.
CVSS v2 Base Score: 4.3 (AV:N/AC:M/Au:N/C:N/I:P/A:N)

ID: CVE-2013-1493
Title: Oracle Java SE JVM 2D Subcomponent Remote Code Execution
Vulnerability (Oracle Security Alert for CVE-2013-1493)
Vendor: Oracle
Description: The color management (CMM) functionality in the 2D
component in Oracle Java SE 7 Update 15 and earlier, 6 Update 41 and
earlier, and 5.0 Update 40 and earlier allows remote attackers to
execute arbitrary code or cause a denial of service (crash) via an image
with crafted raster parameters, which triggers (1) an out-of-bounds read
or (2) memory corruption in the JVM, as exploited in the wild in
February 2013.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
