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

Title: GNU wget FTP Symlink Arbitrary Filesystem Access Vulnerability
Description: GNU Wget versions prior to 1.16 are vulnerable a symlink
attack (CVE-2014-4877) when running in recursive mode with a FTP target.
This vulnerability allows an attacker operating a malicious FTP server
to create arbitrary files, directories, and symlinks on the user’s
filesystem.

Snort SID: Detection Pending

Title: Running “strings” on Untrusted File is a Security Hazard (CVE-2014-8485)
Description: The strings utility on Linux leverages the common libbfd
infrastructure to detect supported executable formats and “optimize” the
process by extracting text only from specific sections of the file.
However, the libbfd library has been discovered to contain very limited
range checking indicating it is likely vulnerable to exploit.

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-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-2013-6221
Title: HP Service Virtualization 3.0 Remote Code Execution Vulnerability
Vendor: HP
Description: Directory traversal vulnerability in CommunicationServlet
in HP Service Virtualization 3.x before 3.50.1, when the AutoPass
license server is enabled, allows remote attackers to create arbitrary
files and consequently execute arbitrary code via unspecified vectors,
aka ZDI-CAN-2031.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/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)

ID: CVE-2013-7331
Title: Microsoft XMLDOM ActiveX Control Multiple Information Disclosure
Vulnerabilities
Vendor: Microsoft
Description: The Microsoft.XMLDOM ActiveX control in Microsoft Windows
8.1 and earlier allows remote attackers to determine the existence of
local pathnames, UNC share pathnames, intranet hostnames, and intranet
IP addresses by examining error codes, as demonstrated by a res:// URL,
and exploited in the wild in February 2014.
CVSS v2 Base Score: 5.8 (AV:N/AC:M/Au:N/C:P/I:N/A:P)

ID: CVE-2014-0160
Title: OpenSSL TLS Heartbeat Extension Buffer Oveflow Information
Disclosure Vulnerability (Heartbleed)
Vendor: OpenSSL Project
Description: The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1
before 1.0.1g do not properly handle Heartbeart Extension packets, which
allows remote attackers to obtain sensitive information from process
memory via crafted packets that trigger a buffer over-read, as
demonstrated by reading private keys, related to d1_both.c and t1_lib.c.
CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:P/I:N/A:N)
