TOP VULNERABILITY THIS WEEK: glibc Project Releases Patch to Address

Critical Buffer Overflow Flaw in getaddrinfo()


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

Title: glibc Project Releases Patch to Address Critical Buffer Overflow
Flaw in getaddrinfo()
Description: The glibc project has released a security advisory to
address CVE-2015-7547, a stack-based buffer overflow flaw which was
discovered by Google and Red Hat security researchers. This
vulnerability manifests as a flaw in the glibc client-side DNS resolver
where mismanagement of buffers in memory could potentially result in
remote code execution. Red Hat researchers note that “it should be
possible to write correctly formed DNS responses with attacker
controlled payloads that will penetrate a DNS cache hierarchy and
therefore allow attackers to exploit machines behind such caches.”
Google researchers also note that all glibc versions since 2.9 are
affected by this flaw. The glibc project has released a patch to address
this vulnerability.

Snort SID: Detection pending

Title: Cisco Releases Security Advisory to Address Buffer Overflow Flaw
in ASA Software
Description: Cisco has released a critical security advisory to address
CVE-2016-1287, a buffer overflow vulnerability in Cisco ASA software.
CVE-2016-1287 manifests as a result of the system improperly handling
fragmented IKEv1/v2 payloads, potentially resulting in remote code
execution. Note that “[t]his vulnerability affects systems configured
in routed firewall mode only and in single or multiple context mode.”
Additionally, “only traffic directed to the affected system can be used
to exploit this vulnerability.” Cisco has released an update to address
this flaw.

Snort SID: 36903, released Nov 2015

Title: Blue Frost Security Releases Advisory Over FireEye Detection
Evasion That Could Lead Whitelisting Arbitrary Malware
Description: Blue Frost Security has released an advisory discussing a
vulnerability in FireEye Operating System (FEOS) that has been patched.
The flaw in question manifests as an “analysis engine evasion” that
could allow an attacker to bypass and evade “FireEye’s
virtualization-based dynamic analysis on Windows and add arbitrary
binaries to the internal whitelist of binaries.” FireEye has released a
fix for this issue as 2015-10-21.

Title: VMware Reissues Patch for vCenter Server Due to Patch for
CVE-2015-2342 Being Incomplete
Description: VMware has reissued a patch for vCenter Server after
discovering that the patch addressing CVE-2015-2342 was incomplete.
CVE-2015-2342 is a remote code execution vulnerability within the
vCenter Server JMX RMI service which manifests due to an insecure
configuration of the JMX RMI service. VMware notes that Windows Firewall
can mitigate the remote code execution vulnerability on systems where
vCenter Server Windows is installed, but will not mitigate the local
privilege escalation vulnerability. The reissued patched is available
from VMware Knowledge Base (KB) article 2144428.
