docker: insecure opening of file-descriptor allows privilege escalation

The runc component used by docker exec feature of docker allowed additional container processes to be ptraced by the pid 1 of the container. This allows the main processes of the container, if running as root, to gain low-level access to these new processes during initialization. An attacker can,...

Android debuggerd.cpp elevation of privilege vulnerability

Android is a mobile operating system based on the Linux open kernel, and Debuggerd is one of the system startup process components. An elevation of privilege vulnerability exists in the debuggerd/debuggerd.cpp file in Android Debuggerd, which stems from the program's failure to properly handle th...

The vulnerability of the Linux operating system, which allows a hacker to trigger a service failure or increase their privileges.

The vulnerability of the Linux operating system’s kernel is related to the improper limitation on the use of non- canonical values for the saved RIP address during system calls that do not utilize IRET. Exploiting this vulnerability can allow an attacker, operating locally, to increase their...

Vulnerability of the Linux operating system, leading to the exposure of information

Overflow in the getdumpable function of the ptrace subsystem leads to the disclosure of information. Only those systems are vulnerable where the sysctl fs.suiddumpable variable is set to 2 it is not the default value...

After reviewing the operations listed, you can then decide whether you really want these things to happen or not. What is this sorcery?!? maybe...

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...

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...
