The vulnerability of the load_aout_binary() function in the Linux operating system’s kernel allows a hacker to bypass the ASLR protection mechanism.

The vulnerability of the loadaoutbinary function in the Linux operating system arises due to synchronization errors when using shared resources. Exploiting this vulnerability can allow an attacker to bypass the ASLR protection mechanism in programs with setuid a.out...

PT-2020-6251 · Sane +4 · Sane-Backends +4

Name of the Vulnerable Software and Affected Versions: SANE Backends versions prior to 1.0.30 Description: The issue is related to an out-of-bounds read in the SANE Backends interface, which provides access to scanning devices. This may allow a malicious device connected to the same local network...

Session fixation

rConfig 3.9.4 is vulnerable to session fixation because session expiry and randomization are mishandled. The application can reuse a session via PHPSESSID. Also, an attacker can exploit this vulnerability in conjunction with CVE-2020-12256 or CVE-2020-12259...

Kernel: net: using kernel space address bits to derive IP ID may potentially break KASLR

A flaw was found in the way the Linux kernel derived the IP ID field from a partial kernel space address returned by a nethashmix function. A remote user could observe this IP ID field to extract the kernel address bits used to derive its value, which may result in leaking the hash key and...

Denial Of Service (DoS)

ruby is vulnerable to denial of service. A denial of service flaw was found in the implementation of associative arrays hashes in Ruby. An attacker able to supply a large number of inputs to a Ruby application such as HTTP POST request parameters sent to a web application that are used as keys wh...

Protection Mechanism Bypass

The kernel is vulnerable to Protection Mechanism Bypass. The startcode and endcode values in "/proc/pid/stat" were not protected. In certain scenarios, this flaw could be used to defeat Address Space Layout Randomization ASLR...

CVE-2018-21076

An issue was discovered on Samsung mobile devices with N7.x Exynos8890/8895 chipsets software. There is information disclosure a KASLR offset in the Secure Driver via a modified trustlet. The Samsung ID is SVE-2017-10987 April 2018...

Denial Of Service (DoS)

Kernel is vulnerable to denial of service DoS because kernel space address bits to derive IP ID may potentially break KASLR...

kernel: ASLR bypass for setuid binaries due to late install_exec_creds()

A flaw in the loadelfbinary function in the Linux kernel allows a local attacker to leak the base address of .text and stack sections for setuid binaries and bypass ASLR because installexeccreds is called too late in this function...

HTTP Asynchronous Reverse Shell - Asynchronous Reverse Shell Using The HTTP Protocol

Today there are many ways to create a reverse shell in order to be able to remotely control a machine through a firewall. Indeed, outgoing connections are not always filtered. However security software and hardware IPS, IDS, Proxy, AV, EDR... are more and more powerful and can detect these attack...

Security Bulletin: A vulnerability affects the Cordova platform packaged with Rational Application Developer (CVE-2015-8320)

Summary A vulnerability has been discovered that affects the Cordova platform packaged with Rational Application Developer. Vulnerability Details CVEID: CVE-2015-8320 DESCRIPTION: Apache Cordova Android could allow a remote attacker to bypass security restrictions, caused by weak randomization of...

CVE-2019-19126

A vulnerability was discovered in glibc where the LDPREFERMAP32BITEXEC environment variable is not ignored when running binaries with the setuid flag on x8664 architectures. This allows an attacker to force system to utilize only half of the memory making the system think the software is 32-bit...

DEBIAN-CVE-2019-19126

On the x86-64 architecture, the GNU C Library aka glibc before 2.31 fails to ignore the LDPREFERMAP32BITEXEC environment variable during program execution after a security transition, allowing local attackers to restrict the possible mapping addresses for loaded libraries and thus bypass ASLR for...

kernel: Linux stack ASLR implementation Integer overflow

An integer overflow flaw was found in the way the Linux kernel randomized the stack for processes on certain 64-bit architecture systems, such as x86-64, causing the stack entropy to be reduced by four...

ALPINE-CVE-2019-15681

LibVNC commit before d01e1bb4246323ba6fcee3b82ef1faa9b1dac82a contains a memory leak CWE-655 in VNC server code, which allow an attacker to read stack memory and can be abused for information disclosure. Combined with another vulnerability, it can be used to leak stack memory and bypass ASLR. Thi...
