CVE-2019-15790

Apport reads and writes information on a crashed process to /proc/pid with elevated privileges. Apport then determines which user the crashed process belongs to by reading /proc/pid through getpidinfo in data/apport. An unprivileged user could exploit this to read information about a privileged...

kernel: Unprivileged users able to inspect kernel stacks of arbitrary tasks

An issue was discovered in the procpidstack function in fs/proc/base.c in the Linux kernel. An attacker with a local account can trick the stack unwinder code to leak stack contents to userspace. The fix allows only root to inspect the kernel stack of an arbitrary task...

Ubuntu 16.04 LTS : Sudo vulnerabilities (USN-3968-1)

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3968-1 advisory. Florian Weimer discovered that Sudo incorrectly handled the noexec restriction when used with certain applications. A local attacker could possibly use...

CVE-2019-11190

The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs such as /bin/su because installexeccreds is called too late in loadelfbinary in fs/binfmtelf.c, and thus the ptracemayaccess check has a race condition when reading /proc/pid/stat...

Уязвимость пакета linux-astra-modules операционной системы Astra Linux связана с ошибкой назначения прав доступа, приводящей к возможности обхода замкнутой программной среды ЗПС через запись в /proc/$PID/mem. Эксплуатация уязвимости может позволить нарушителю обойти заданные правила политики...

DEBIAN-CVE-2018-17972

An issue was discovered in the procpidstack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents...

PT-2018-2382

Name of the Vulnerable Software and Affected Versions Linux kernel versions through 4.18.11 Description An issue in the proc pid stack function allows a local attacker to exploit racy stack unwinding and leak kernel task stack contents due to inadequate access control. This enables an attacker to...

CVE-2017-2618

A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty null write to this file can crash the system by causing the system to attempt to access unmapped kernel memory...

CVE-2017-2618: Off-by-one Error

A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty null write to this file can crash the system by causing the system to attempt to access unmapped kernel memory...

CVE-2017-18344

CVE-2017-18344 affects the Linux kernel before 4.14.8. The timer_create syscall in kernel/time/posix-timers.c fails to validate sigevent->sigev_notify, causing out-of-bounds access in show_timer when /proc/$PID/timers is read and enabling a local user to read arbitrary kernel memory on builds ...

CVE-2018-1120

A flaw was found affecting the Linux kernel before version 4.17. By mmaping a FUSE-backed file onto a process's memory containing command line arguments or environment strings, an attacker can cause utilities from psutils or procps such as ps, w or any other program which makes a read call to the...

CVE-2018-1121

procps-ng, procps is vulnerable to a process hiding through race condition. Since the kernel's procpidreaddir returns PID entries in ascending numeric order, a process occupying a high PID can use inotify events to determine when the process list is being scanned, and fork/exec to obtain a lower...

Security update for sudo (important)

This update for sudo fixes the following issues: CVE-2017-1000367: - Due to incorrect assumptions in /proc/pid/stat parsing, a local attacker can pretend that his tty is any file on the filesystem, thus gaining arbitrary file write access on SELinux-enabled systems. bsc1039361 - Fix FQDN for...

Ubuntu 14.04 LTS / 16.04 LTS : Sudo vulnerability (USN-3304-1)

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3304-1 advisory. It was discovered that Sudo did not properly parse the contents of /proc/pid/stat when attempting to determine its controlling tty. A local attacker i...
