Ilja van Sprundel, an IOActive security researcher, discovered several issues in the way the libXfont library handles the responses it receives from XFS servers. Mr. van Sprundel has worked with X.Org’s security team to analyze, confirm, and fix these issues. Most of these issues stem from libXfont trusting the font server to send valid protocol data and not verifying that the values will not overflow or cause other damage. This code is commonly called from the X server when an X Font Server is active in the font path, so…
Attackers can steal Facebook access tokens to impersonate Facebook users and perform malicious actions that include, but are not limited to, posting content on behalf of users and accessing friend lists.
A non-privileged use could cause a local Denial-of-Service (DoS) condition by triggering a kernel panic through a malformed ELF executable.
The WeMo devices connect to the Internet using the STUN/TURN protocol. This gives users remote control of the devices and allows them to perform firmware updates from anywhere in the world. A generated GUID is the primary source of access control. WeMo also uses a GPG-based, encrypted firmware distribution scheme to maintain device integrity during updates. Unfortunately, attackers can easily bypass most of these features due to the way they are currently implemented in the WeMo product line. The command for performing firmware updates is initiated over the Internet from…
While performing a routine world-writable file scan, one of IOActive’s consultants discovered that the Steam Client for Mac OS X creates world-writable shell scripts when installing games.
OleumTech has manufactured industrial wireless solutions for almost 15 years, providing visibility to disparate assets for major Oil & Gas producers for near real-time optimization decisions, resource deployment, and regulatory compliance. OleumTech also manufacturers industrial automation systems that represents the new paradigm of remote monitoring and control for industries, such as Oil & Gas, Refining, Petro-chemical, Utilities, and Water/Wastewater. In June 2013, IOActive Labs reported four critical vulnerabilities in OleumTech’s wireless sensor network to ICS-CERT. To date, IOActive Labs is not aware of any fixes released by OleumTech.
This advisory is a follow-up to the alerts titled “ICS-ALERT-12-166-01 Sielco Sistemi Winlog Buffer Overflow” that was published June 14, 2012, and “ICS-ALERT-12-179-01 Sielco Sistemi Winlog Multiple Vulnerabilities” that was published June 27, 2012, on the ICS-CERT web page.
The affected products provide communication between the communications bus and I/O modules. According to TURCK, the BL20 and BL67 are deployed across several sectors. These include agriculture and food, automotive, and critical manufacturing. TURCK estimates that these products are used primarily in the United States and Europe with a small percentage in Asia. This vulnerability allows an attacker to remotely access the device through its embedded FTP server by using the undocumented, hard-coded credentials. The attacker can then install a trojanized firmware to control communications and processes.
X.Org believes all prior versions of these libraries contain the vulnerabilities discussed in this document, dating back to their introduction. Versions of the X libraries built on top of the Xlib bridge to the XCB framework are vulnerable to fewer issues than those without. This is due to the added safety and consistency assertions in the XCB calls to read data from the network. However, most of these vulnerabilities are not caught by such checks.
The United States Emergency Alert System (EAS) in 1997 replaced the older and better known Emergency Broadcast System (EBS) used to deliver local or national emergency information. The EAS is designed to “enable the President of the United States to speak to the United States within 10 minutes” after a disaster occurs. In the past, these alerts were passed from station to station using the Associated Press (AP) or United Press International (UPI) “wire services”, which connected to television and radio stations around the U.S. Whenever the station received an…
