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-2014-8517
Title: tnftp Command Execution Vulnerability
Vendor: FreeBSD
Description: The fetch_url function in usr.bin/ftp/fetch.c in tnftp, as
used in NetBSD 5.1 through 5.1.4, 5.2 through 5.2.2, 6.0 through 6.0.6,
and 6.1 through 6.1.5 allows remote attackers to execute arbitrary
commands via a | (pipe) character at the end of an HTTP redirect.
CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)

ID: CVE-2014-6324
Title: Microsoft Windows Kerberos Checksum Privilege Escalation
Vulnerability (MS14-068)
Vendor: Microsoft
Description: The Kerberos Key Distribution Center (KDC) in Microsoft
Windows Server 2003 SP2, Windows Vista SP2, Windows Server 2008 SP2 and
R2 SP1, Windows 7 SP1, Windows 8, Windows 8.1, and Windows Server 2012
Gold and R2 allows remote authenticated domain users to obtain domain
administrator privileges via a forged signature in a ticket, as
exploited in the wild in November 2014, aka “Kerberos Checksum
Vulnerability.”
CVSS v2 Base Score: 9.0 (AV:N/AC:L/Au:S/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)

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)
