Speaking at WithSecure’s annual conference, Mikko Hyppönen discussed the threat landscape between the two nations

A critical security flaw has been uncovered in UNISOC's smartphone chipset that could be potentially weaponized to disrupt a smartphone's radio communications through a malformed packet. "Left unpatched, a hacker or a military unit can leverage such a vulnerability to neutralize communications in a specific location," Israeli cybersecurity company Check Point said in a report shared with The

The U.S. Department of Justice (DoJ) on Wednesday announced the seizure of three domains used by cybercriminals to trade stolen personal information and facilitate distributed denial-of-service (DDoS) attacks for hire. This includes weleakinfo[.]to, ipstress[.]in, and ovh-booter[.]com, the former of which allowed its users to traffic hacked personal data and offered a searchable database

BigBlueButton is an open source web conferencing system. Versions starting with 2.2 and prior to 2.3.19, 2.4.7, and 2.5.0-beta.2 are vulnerable to regular expression denial of service (ReDoS) attacks. By using specific a RegularExpression, an attacker can cause denial of service for the bbb-html5 service. The useragent library performs checking of device by parsing the input of User-Agent header and lets it go through lookupUserAgent() (alias of useragent.lookup() ). This function handles input by regexing and attackers can abuse that by providing some ReDos payload using `SmartWatch`. The maintainers removed `htmlclient/useragent` from versions 2.3.19, 2.4.7, and 2.5.0-beta.2. As a workaround, disable NginX forwarding the requests to the handler according to the directions in the GitHub Security Advisory.

We break down three ways DNS filtering can help save your business from cyberattacks. The post 3 ways DNS filtering can save SMBs from cyberattacks appeared first on Malwarebytes Labs.

Ubuntu Security Notice 5456-1 - It was discovered that ImageMagick incorrectly handled memory under certain circumstances. If a user were tricked into opening a specially crafted image, an attacker could possibly exploit this issue to cause a denial of service or other unspecified impact.

EnemyBot DDoS botnet is rapidly weaponizing security bugs disclosed in CMS systems like WordPress plug-ins, Android devices, commercial Web servers, and other enterprise applications.

Ubuntu Security Notice 5457-1 - A large number of security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.

Ubuntu Security Notice 5443-2 - Kyle Zeng discovered that the Network Queuing and Scheduling subsystem of the Linux kernel did not properly perform reference counting in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or execute arbitrary code. Jann Horn discovered that the Linux kernel did not properly enforce seccomp restrictions in some situations. A local attacker could use this to bypass intended seccomp sandbox restrictions.

Ubuntu Security Notice 5454-2 - USN-5454-1 fixed several vulnerabilities in CUPS. This update provides the corresponding update for Ubuntu 16.04 ESM. Joshua Mason discovered that CUPS incorrectly handled the secret key used to access the administrative web interface. A remote attacker could possibly use this issue to open a session as an administrator and execute arbitrary code.
