TOP VULNERABILITY THIS WEEK: Google Releases Monthly Security Bulletin for Android

NOTABLE RECENT SECURITY ISSUES

SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Google Releases Monthly Security Bulletin for Android
Description: Google has released its monthly security bulletin for Android and Nexus devices. As with other Android and Nexus security bulletins Google has released, there are two patch levels that will be made available for manufacturers and consumers. In total, 75 vulnerabilities were patched with 11 being classified “critical”, 44 classified “high”, and 20 classified “moderate”. All vulnerabilities classified “critical” are privilege escalation flaws that could allow an application to execute code with kernel-level privilege and force the user to reflash the operating system if a device becomes compromised. Nexus devices will have a security update available for download on December 5th. Other devices should receive an update from the manufacturer as long as the device is currently supported.

Snort SID: Detection pending release of vulnerability information

Title: “Backdoor” in Sony IPELA Engine IP Camera Fixed
Description: Researchers have identified what appears to be a “backdoor” in Sony IPELA Engine IP Cameras. This undocumented functionality was discovered via identifying a hardcoded password hash in the firmware and a mechanism to enable Telnet remotely via a specifically formatted HTTP request. While Sony has addressed the issue by releasing a firmware update, they have not commented on the nature of the undocumented functionality.

Title: Buffer Overflow Vulnerability Identified in BSD libc
Description: Researchers have identified a buffer overflow vulnerability in BSD libc. CVE-2016-6559 manifests due to “improper bounds checking of the obuf variable in the link_ntoa() function in linkaddr.c” and “may allow an attacker to read or write from memory”. The impact of this vulnerability is not fully know as the “impact and severity depends on the method of exploit and how the library is used by applications.” BSD libc has been updated to address this flaw. Note that this affects FreeBSD, OpenBSD, and Darwin (Apple macOS). Other distributions may be affected.
