NetBSD virecover Script Denial of Service Vulnerability

NetBSD is a BSD-based UNIX-like operating system. A denial of service vulnerability exists in the NetBSD virecover script. An attacker can exploit this vulnerability to delete any file in the root directory of the target system, resulting in a DOS condition...

NetBSD Context Handling Elevation of Privilege Vulnerability

NetBSD is a BSD-based UNIX-like operating system. An elevation of privilege vulnerability exists in NetBSD context handling. The vulnerability is due to mishandling by the NetBSD kernel of requests and system calls to applications running with normal user privileges up. Allowing a local attacker ...

Unsupervised Coverage-Guided Kernel Fuzzer: syzkaller

syzkaller is an unsupervised coverage-guided kernel fuzzer. Linux kernel fuzzing has the most support, akaros, freebsd, fuchsia, netbsd and windows are supported to varying degrees. Initially, syzkaller was developed with Linux kernel fuzzing in mind, but now it’s being extended to support other ...

[SECURITY] Fedora 26 Update: ejabberd-17.01-3.fc26

ejabberd is a Free and Open Source distributed fault-tolerant Jabber/XMPP server. It is mostly written in Erlang, and runs on many platforms tested on Linux, FreeBSD, NetBSD, Solaris, Mac OS X and Windows NT/2000/XP...

The vulnerability in the implementation of the operating system NetBSD’s stack protection mechanism allows a hacker to execute arbitrary code.

The vulnerability of the Linux kernel’s stack protection mechanism is related to deficiencies in access control. Exploiting this vulnerability allows a malicious actor to execute arbitrary code remotely, using specially crafted binary files with setuid attributes as,usr,bin,at...

The vulnerability of the qsort function in the NetBSD operating system, which allows a hacker to execute arbitrary code (memory corruption).

The vulnerability of the qsort function in the NetBSD operating system is related to resource management errors. Exploiting this vulnerability allows a remote attacker to execute arbitrary code memory consumption using a specially crafted input array...

The vulnerability of the NetBSD operating system, which allows a hacker to execute arbitrary code

The vulnerability of the NetBSD operating system arises from the operation of the ld.so command outside the buffer on the stack, when the ASRL function is enabled. Exploiting this vulnerability allows a remote attacker to execute arbitrary code...

Linux in the Stack Clash vulnerabilities that may be exploited by hackers to obtain local root privileges-bug warning-the black bar safety net

Last month, Qualys security researchers in a variety of Unix-based Systems found on called the“Stack Clash”the vulnerability could allow an attacker on a UNIX system to gain root privileges and take over the attack computer. Currently security researchers discovered this flaw and are working with...

blkif responses leak backend stack data

ISSUE DESCRIPTION The block interface response structure has some discontiguous fields. Certain backends populate the structure fields of an otherwise uninitialized instance of this structure on their stacks, leaking data through the internal or trailing padding field. IMPACT A malicious...

Visualizing the Stack Clash Vulnerability with Dashboards

Security teams should apply vendor patches immediately to protect their Linux, OpenBSD, NetBSD, FreeBSD and Solaris infrastructure from The Stack Clash vulnerability also see the security advisory. To help in that effort, this blog post describes a new built-in Qualys AssetView dashboard to...

CVE-2017-1000375

NetBSD maps the run-time link-editor ld.so directly below the stack region, even if ASLR is enabled, this allows attackers to more easily manipulate memory leading to arbitrary code execution. This affects NetBSD 7.1 and possibly earlier versions...

CVE-2017-1000378

The NetBSD qsort function is recursive, and not randomized, an attacker can construct a pathological input array of N elements that causes qsort to deterministically recurse N/4 times. This allows attackers to consume arbitrary amounts of stack memory and manipulate stack memory to assist in...
