TOP VULNERABILITY THIS WEEK: Privilege Escalation Vulnerability within
the Linux Kernel Identified and Patched
NOTABLE RECENT SECURITY ISSUES SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP
Title: Privilege Escalation Vulnerability within the Linux Kernel
Identified and Patched
Description: Researchers at Perception Point have identified a privilege
escalation vulnerability within the Linux kernel. CVE-2016-0728
manifests as a reference leak in the keyrings facility of the Linux
kernel that can be used to overflow a key object’s usage field. A lower
privileged user who writes an application that exploits this
vulnerability could obtain root access and thus, complete control of the
system. This vulnerability impacts Linux kernel versions 3.8 and higher
and appears to have existed since 2012. This vulnerability within the
Linux kernel has been fixed by the Red Hat Security Team. Patches for
Linux distributions affected by the vulnerability are being released.

Title: OpenSSH Fixes Vulnerability That Could Leak Private Crypto Keys
Description: Researchers at Qualys have identified a vulnerability
within OpenSSH that could result in the client “leaking client memory
to the server, including private client user keys.” This vulnerability
manifests from code in the OpenSSH client that has shipped and is
enabled by default to allow the resumption of SSH connections. Note that
exploitation of this vulnerability is primarily restricted to malicious
or compromised servers as “authentication of the server host key
prevents exploitation by a man-in-the-middle.” OpenSSH has addressed
this vulnerability along with an out-of-bounds read violation in it’s
latest release.

Title: Apple Releases Security Updates for OS X, iOS, and Safari
Description: Apple has released security updates for a large number of
currently supported products such as Mac OS X, iOS, and Safari. The
latest update for iOS addresses 13 vulnerabilities while the OS X
Security Update and Safari security update address 9 and 6
vulnerabilities respectively. Note that the time-zone related bug in iOS
that results in a misrepresentation of device battery levels was not
addressed in this update.
