TOP VULNERABILITY THIS WEEK: Apple Patches Trio of Vulnerabilities (AKA “Trident”) in Mac OS X and Safari


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

Title: Apple Patches Trio of Vulnerabilities (AKA “Trident”) in Mac OS X and Safari
Description: Apple has released two security advisories for Mac OS X and Safari to address the three iOS 0-day vulnerabilities identified by Citizen Labs and Lookout Security targeting human rights activists. The three vulnerabilities (CVE-2016-4655, CVE-2016-4656, CVE-2016-4657) were all recently patched in iOS 9.3.5, but had not yet been patched for Mac OS X and Safari.

Title: Cisco Issues Two Critical Security Advisories for Sx 220 Series Switches and WebEx Meeting Center
Description: Cisco has released a pair of critical security advisories for Cisco Small Business 220 Series Smart Plus (Sx220) Switches and WebEx Meeting Center. The flaw in Sx200 series switches, CVE-2016-1473, is an unauthorized access vulnerability in the SNMP functionality where an attackers could gain “unauthorized access to SNMP objects on an affected device.” The other flaw affecting WebEx Meeting Center, CVE-2016-1464, is an arbitrary code execution flaw which manifests due to improper handling of user-supplied files. Cisco has released software and firmware updates that address both flaws. Cisco also notes that no workarounds are available for either flaw.

Title: Google Releases Patch for Critical Memory Dumping Flaw in Nexus 5X
Description: Researchers at IBM X-Force have identified a critical flaw in certain Nexus 5X bootloaders that could potentially allow an attacker to dump memory of the device. The vulnerability in question is exploitable via “physical or nonphysical attackers with Android Debug Bridge (ADB) access to the device.” If an attacker issues a ‘fastboot oem panic’ command “via the fastboot USB interface,” the device would crash and “cause the bootloader to expose a serial-over-USB connection.” This “would allow an attacker to obtain a full memory dump of the device.” Google has acknowledged the issue and have patched the vulnerability.
