TOP VULNERABILITY THIS WEEK: Google Patches Several Major

Vulnerabilities in January Android Security Bulletin


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Google Patches Several Major Vulnerabilities in January Android
Security Bulletin
Description: Google has released its January Security Bulletin for Nexus
devices addressing several critical vulnerabilities with Android. One
notable vulnerability addressed this month is a remote code execution
vulnerability in Mediaserver that manifests as a failure to properly
handle specially crafted media files. Mediaserver is core part of
Android that is used to process and decode media files, such as MMS and
browser playback of media. Other vulnerabilities that were patched
include privilege escalation flaws, information disclosure flaws, and a
denial-of-service flaw. Updating to build LMY49F or later and/or Android
6.0 with Security Patch Level of January 1, 2016 addresses these flaws.
In addition, partners have been notified about this vulnerabilities and
provided updates to address these flaws in respective firmware releases.

Snort SID: Detection pending release of vulnerability information

Title: Comcast XFINITY Home Security Systems Found to Improperly Handle
Wireless Communication Disruptions/Failures with Sensors
Description: Researchers at Rapid7 have found that the Comcast XFINITY
Home Security System fails to properly handle communication disruptions
between the base station and sensors. The base station’s software fails
to handle communication disruptions by not triggering an alert should
sensors cease communicating, thereby potentially reporting an incorrect
state (such a door reporting as “closed” when it is actually “open”).
An attacker who disrupts communications over the 2.4 GHz radio frequency
band to prevent sensors from communicating with the base station could
exploit this flaw to enter a domicile and avoid triggering Home Security
system alarm events (even in an “armed” state). Currently, no known
workaround or mitigate to address this vulnerability is known or
available.

Title: Cisco Jabber Client Found Vulnerable to STARTTLS downgrade attack
Description: Researchers at Synacktiv have found that the Cisco Jabber
client is vulnerable to a STARTTLS downgrade attack. The vulnerability
manifests due to a failure to validate if a XMPP connection has been
established over TLS. A man-in-the-middle attacker could exploit this
flaw and tamper with the XMPP connection to avoid TLS negotiation,
causing the client to establish a XMPP connection over cleartext. Cisco
has released a security advisory and updated software to address this
vulnerability.
