Linux Kernel /proc/pid/syscall information disclosure vulnerability

Summary An information disclosure vulnerability exists in the /proc/pid/syscall functionality of Linux Kernel 5.1 Stable and 5.4.66. More specifically, this issue has been introduced in v5.1-rc4 commit 631b7abacd02b88f4b0795c08b54ad4fc3e7c7c0 and is still present in v5.10-rc4, so it’s likely that...

ansible: svn module leaks password when specified as a parameter

A flaw was found in Ansible Engine. When a password is set with the argument "password" of svn module, it is used on svn command line, disclosing to other users within the same node. An attacker could take advantage by reading the cmdline file from that particular PID on the procfs...

ansible: insecure temporary directory when running become_user from become directive

A race condition flaw was found in Ansible Engine when running a playbook with an unprivileged become user. When Ansible needs to run a module with become user, the temporary directory is created in /var/tmp. This directory is created with "umask 77 && mkdir -p "; this operation does not fail if...

Denial Of Service (DoS)

Kernel is vulnerable to denial of service DoS. The proc file system could allow a local, unprivileged user to obtain sensitive information or possibly cause integrity issues...

Information Disclosure

kernel is vulnerable to information disclosure. The vulnerability exists as /proc/PID/io is world-readable by default. Previously, these files could be read without any further restrictions. A local, unprivileged user could read these files, belonging to other, possibly privileged processes to...

Information Disclosure

kernel is vulnerable to information disclosure. An information leak in bcmconnect in the Controller Area Network CAN Broadcast Manager implementation could allow a local, unprivileged user to leak kernel mode addresses in /proc/net/can-bcm...

Information Disclosure

kernel is vulnerable to information disclosure. An information leak was found in the Linux kernel's taskshowregs implementation. On IBM S/390 systems, a local, unprivileged user could use this flaw to read /proc/PID/status files, allowing them to discover the CPU register values of processes...

Information Disclosure

The kernel-rt is vulnerable to Information Disclosure. Kees Cook and Steve Beattie discovered a race condition in the /proc code in the Linux kernel. This could lead to information in the "/proc/pid/maps" and "/proc/pid/smaps" files being leaked to users who would otherwise not have access to thi...

Denial Of Service (DoS)

The kernel package is vulnerable to denial of service DoS. The RHSA-2009:0225 update introduced a rewrite attack flaw in the docoredump function. A local attacker able to guess the file name a process is going to dump its core to, prior to the process crashing, could use this flaw to append data ...

runc: AppArmor/SELinux bypass with malicious image that specifies a volume at /proc

runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfslinux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc directory...

Race condition

A race condition flaw was found in Ansible Engine 2.7.17 and prior, 2.8.9 and prior, 2.9.6 and prior when running a playbook with an unprivileged become user. When Ansible needs to run a module with become user, the temporary directory is created in /var/tmp. This directory is created with "umask...

Linux kernel information disclosure vulnerability (CNVD-2020-16637)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the fs/proc/base.c file in Linux kernel 3.1 and earlier versions. A local attacker can exploit this vulnerability to obtain sensitiv...

USN-4297-1 runc vulnerabilities

It was discovered that runC incorrectly checked mount targets. An attacker with a malicious container image could possibly mount over the /proc directory and escalate privileges. This issue only affected Ubuntu 18.04 LTS. CVE-2019-16884 It was discovered that runC incorrectly performed access...
