Another dangerous vulnerability has been discovered in Linux kernel that dates back to 2009 and affects a large number of Linux distros, including Red Hat, Debian, Fedora, OpenSUSE, and Ubuntu.
The latest Linux kernel flaw (CVE-2017-2636), which existed in the Linux kernel for the past seven years, allows a local unprivileged user to gain root privileges on affected systems or cause a denial
No software is immune to being Hacked! Not even Linux.
A security researcher has discovered a critical vulnerability in Ubuntu Linux operating system that would allow an attacker to remotely compromise a target computer using a malicious file.
The vulnerability affects all default Ubuntu Linux installations versions 12.10 (Quantal) and later.
Researcher Donncha O’Cearbhaill discovered the
A 5-year-old serious privilege-escalation vulnerability has been discovered in Linux kernel that affects almost every distro of the Linux operating system, including Redhat, and Ubuntu.
Over a month back, a nine-year-old privilege-escalation vulnerability, dubbed “Dirty COW,” was discovered in the Linux kernel that affected every distro of the open-source operating system, including Red Hat,
A hacker with little more than a minute can bypass the authentication procedures on some Linux systems just by holding down the Enter key for around 70 seconds.
The result? The act grants the hacker a shell with root privileges, which allows them to gain complete remote control over encrypted Linux machine.
The security issue relies due to a vulnerability (CVE-2016-4484) in the
Unlike specially crafted malware specifically developed to take advantage of Windows operating system platform, cyber attackers have started creating cross-platform malware for wider exploitation.
Due to the rise in popularity of Mac OS X and other Windows desktop alternatives, hackers have begun designing cross-platform malware modularly for wide distribution.
Cross-platform malware is
An estimated 80 percent of Android smartphones and tablets running Android 4.4 KitKat and higher are vulnerable to a recently disclosed Linux kernel flaw that allows hackers to terminate connections, spy on unencrypted traffic or inject malware into the parties’ communications.
Even the latest Android Nougat Preview is considered to be vulnerable.

A highly critical vulnerability has been uncovered in the GNU C Library (glibc), a key component of most Linux distributions, that leaves nearly all Linux machines, thousands of apps and electronic devices vulnerable to hackers that can take full control over them.
“glibc reserves 2048 bytes in the stack through alloca() for the DNS answer at _nss_dns_gethostbyname4_r() for hosting responses to a DNS query. Later on, at send_dg() and send_vc(), if the response is larger than 2048 bytes, a new buffer is allocated from the heap and all the information (buffer pointer, new buffer size and response size) is updated.”
“Under certain conditions a mismatch between the stack buffer and the new heap allocation will happen. The final effect is that the stack buffer will be used to store the DNS response, even though the response is larger than the stack buffer and a heap buffer was allocated. This behavior leads to the stack buffer overflow.”
A new critical zero-day vulnerability has been discovered in the Linux kernel that could allow attackers to gain root level privileges by running a malicious Android or Linux application on an affected device.
The critical Linux kernel flaw (CVE-2016-0728) has been identified by a group of researchers at a startup named Perception Point.
