TOP VULNERABILITY THIS WEEK: Cisco Releases Security Advisories for IOS
and IOS XE
NOTABLE RECENT SECURITY ISSUES SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP
Title: Cisco Releases Security Advisories for IOS and IOS XE
Description: Cisco has released their bi-annual IOS Software Security
Advisory bundle. In total, 7 advisories were published, addressing
vulnerabilities in Autonomic Network Infrastructure (ANI), Common
Industrial Protocol (CIP), Multicast Domain Name System (mDNS), TCP,
Virtual Routing and Forwarding (VRF), Internet Key Exchange Version 2
(IKEv2), and Cisco IOS XE Software. These vulnerabilities, if left
unpatched, could allow an attacker to leverage them to perform denial
of service attacks.

Title: GitHub hit with a Massive DDoS Attack
Description: GitHub has been hit with a large scale DDoS attack that has
lasted for five days. While GitHub has experienced some intermittent
interruption of service, it has been largely able to stay online
throughout the DDoS attack. As of 2015-03-31 11:11 UTC, current
mitigations GitHub has in place are holding and the service remains
stable.

RECENT VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM
This is a list of recent vulnerabilities for which exploits are
available. System administrators can use this list to help in
prioritization of their remediation activities. The Qualys Vulnerability
Research Team compiles this information based on various exploit
frameworks, exploit databases, exploit kits and monitoring of internet
activity.
ID: CVE-2015-0313
Title: Adobe Flash Player Use-After-Free Vulnerability
Vendor: Adobe
Description: Use-after-free vulnerability in Adobe Flash Player before
13.0.0.269 and 14.x through 16.x before 16.0.0.305 on Windows and OS X
and before 11.2.202.442 on Linux allows remote attackers to execute
arbitrary code via unspecified vectors, as exploited in the wild in
February 2015, a different vulnerability than CVE-2015-0315,
CVE-2015-0320, and CVE-2015-0322.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2015-0318
Title: Adobe Flash Player Memory Corruption Vulnerability
Vendor: Adobe
Description: Adobe Flash Player before 13.0.0.269 and 14.x through 16.x
before 16.0.0.305 on Windows and OS X and before 11.2.202.442 on Linux
allows attackers to execute arbitrary code or cause a denial of service
(memory corruption) via unspecified vectors, a different vulnerability
than CVE-2015-0314, CVE-2015-0316, CVE-2015-0321, CVE-2015-0329, and
CVE-2015-0330.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2015-0235
Title: Exim GHOST (glibc gethostbyname) Buffer Overflow
Vendor: Exim.org
Description: Heap-based buffer overflow in the
__nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions
before 2.18, allows context-dependent attackers to execute arbitrary
code via vectors related to the (1) gethostbyname or (2) gethostbyname2
function, aka “GHOST.”
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2014-4114
Title: Microsoft Windows OLE - Remote Code Execution “Sandworm” Exploit
(MS14-060)
Vendor: Microsoft
Description: Microsoft Windows Vista SP2, Windows Server 2008 SP2 and
R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2012 Gold
and R2, and Windows RT Gold and 8.1 allow remote attackers to execute
arbitrary code via a crafted OLE object in an Office document, as
exploited in the wild with a “Sandworm” attack in June through October
2014, aka “Windows OLE Remote Code Execution Vulnerability.”
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
ID: CVE-2014-7169
Title: Multiple Vendor Bash Remote Code Execution Vulnerability
Vendor: Multiple Vendors
Description: GNU Bash through 4.3 bash43-025 processes trailing strings
after certain malformed function definitions in the values of
environment variables, which allows remote attackers to write to files
or possibly have unknown other impact via a crafted environment, as
demonstrated by vectors involving the ForceCommand feature in OpenSSH
sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server,
scripts executed by unspecified DHCP clients, and other situations in
which setting the environment occurs across a privilege boundary from
Bash execution. NOTE: this vulnerability exists because of an incomplete
fix for CVE-2014-6271.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2014-6271
Title: Multiple Vendor Bash Remote Code Execution Vulnerability
Vendor: Multiple Vendors
Description: GNU Bash through 4.3 processes trailing strings after
function definitions in the values of environment variables, which
allows remote attackers to execute arbitrary code via a crafted
environment, as demonstrated by vectors involving the ForceCommand
feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache
HTTP Server, scripts executed by unspecified DHCP clients, and other
situations in which setting the environment occurs across a privilege
boundary from Bash execution, aka “ShellShock.” NOTE: the original fix
for this issue was incorrect; CVE-2014-7169 has been assigned to cover
the vulnerability that is still present after the incorrect fix.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
