TOP VULNERABILITY THIS WEEK: Samba Server Uninitialized Pointer Use Flaw
NOTABLE RECENT SECURITY ISSUES SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP
Title: Samba Server Uninitialized Pointer Use Flaw
Description: A critical vulnerability has been disclosed, affecting
certain versions of Samba server. CVE-2015-0240 is a vulnerability
within the Netlogon server implementation in Samba where the service
attempts to perform a free operation on an uninitialized stack pointer.
This could potentially allowing remote attackers to execute arbitrary
code via maliciously crafted packets.

Title: Cisco IOS XR Software IPv6 Malformed Packet Denial of Service Vulnerability
Description: A vulnerability in the parsing of malformed IPv6 packets
in Cisco IOS XR Software for Cisco Network Convergence System 6000 (NCS
6000) and Cisco Carrier Routing System (CRS-X) could allow an
unauthenticated, remote attacker to cause a reload of a line card that
is processing traffic and thus, cause a denial of service. Cisco has
released free software updates that address this vulnerability,
CVE-2015-0618.

Title: Lenovo Superfish Certificate Password Cracked
Description: The passwords for the Superfish certificates used to
man-in-the-middle SSL/TLS traffic on certain Lenovo laptops have been
cracked. The disclosure of these passwords could allow an attacker to
forge certificates that could appear legitimate to Lenovo laptops with
the Superfish root certificates installed and act as a man-in-the-middle
and eavesdrop on otherwise encrypted communications.

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-2015-1497
Title: Persistent Systems Client Automation Command Injection Remote
Code Execution Vulnerability
Vendor: Persistent Systems
Description: radexecd.exe in Persistent Systems Radia Client Automation
(RCA) 7.9, 8.1, 9.0, and 9.1 allows remote attackers to execute
arbitrary commands via a crafted request to TCP port 3465.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2014-7288
Title: Symantec Encryption Management Server - Remote Command Injection
Vendor: Symantec
Description: Symantec PGP Universal Server and Encryption Management
Server before 3.3.2 MP7 allow remote authenticated administrators to
execute arbitrary shell commands via a crafted command line in a
database-backup restore action.
CVSS v2 Base Score: 9.0 (AV:N/AC:L/Au:S/C:C/I:C/A:C)
ID: CVE-2015-0310
Title: Adobe Flash Player Memory Address Randomization Design Error
Security Bypass Vulnerability
Vendor: Adobe
Description: Adobe Flash Player before 13.0.0.262 and 14.x through 16.x
before 16.0.0.287 on Windows and OS X and before 11.2.202.438 on Linux
does not properly restrict discovery of memory addresses, which allows
attackers to bypass the ASLR protection mechanism on Windows, and have
an unspecified impact on other platforms, via unknown vectors, as
exploited in the wild in January 2015.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2014-10021
Title: WordPress WP Symposium 14.11 Shell Upload
Vendor: WP Symposium
Description: Unrestricted file upload vulnerability in UploadHandler.php
in the WP Symposium plugin 14.11 for WordPress allows remote attackers
to execute arbitrary code by uploading a file with an executable
extension, then accessing it via a direct request to the file in
server/php/.
CVSS v2 Base Score: 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)
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)
