Linux kernel elevation of privilege vulnerability (CNVD-2016-01042)

The Linux kernel is an open source, free operating system kernel originally done by Linus Torvalds. A security vulnerability exists in the kernel/ptrace.c file in Linux kernel 4.4.1 and earlier versions, which stems from the program's failure to properly handle uid and gid mappings. A local...

Medium: kernel

Issue Overview: The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service memory consumption by sending each descriptor over a UNIX socket before closing it, related to net/unix/afunix.c and net/unix/garbage.c. CVE-2013-4312 A race condition i...

CVE-2015-8709

kernel/ptrace.c in the Linux kernel through 4.4.1 mishandles uid and gid mappings, which allows local users to gain privileges by establishing a user namespace, waiting for a root process to enter that namespace with an unsafe uid or gid, and then using the ptrace system call. NOTE: the vendor...

Debian Security Advisory DSA 3434-1 (linux - security update)

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak. CVE-2015-7513 It was discovered that a local user permitted to use the x86 KVM subsystem could configure the PIT emulation to cause a denial of service...

Linux kernel networking denial of service vulnerability

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. A security vulnerability exists in the networking implementation process in Linux kernel 4.3.2 and earlier versions used in Android and other products. As the program fails to...

CVE-2013-1958

The scmcheckcreds function in net/core/scm.c in the Linux kernel before 3.8.6 does not properly enforce capability requirements for controlling the PID value associated with a UNIX domain socket, which allows local users to bypass intended access restrictions by leveraging the time interval durin...

Ubuntu Patches Privilege-Escalation Bug

There is a privilege-escalation vulnerability in several versions of Ubuntu that results from the fact that the operating system fails to check permissions when users are creating files in some specific circumstances. Security researcher Philip Pettersson discovered the vulnerability and reported...

Linux Kernel 3.13.0 < 3.19 (Ubuntu 12.04/14.04/14.10/15.04) - 'overlayfs' Local Privilege Escalation (Access /etc/shadow)

The overlayfs filesystem does not correctly check file permissions when creating new files in the upper filesystem directory. This can be exploited by an unprivileged process in kernels with CONFIGUSERNS=y and where overlayfs has the FSUSERNSMOUNT flag, which allows the mounting of overlayfs insi...

Medium: kernel

Issue Overview: fs/namespace.c in the Linux kernel through 3.16.1 does not properly restrict clearing MNTNODEV, MNTNOSUID, and MNTNOEXEC and changing MNTATIMEMASK during a remount of a bind mount, which allows local users to gain privileges, interfere with backups and auditing on systems that had...
