CVE-2020-14367

Chrony before 3.5.1 is vulnerable to a local symlink attack on its PID file in /var/run/chrony. During startup, the PID file is created as root and, per sources, chronyd does not check for an existing symlink with the same file name. A privileged attacker could create a symlink named chrony’s def...

Updated chrony package fixes security vulnerability

Chrony's method of opening its PID file could allow a compromised chrony user account to overwrite files in certain parts of the filesystem with chrony's PID, using a symlink attack CVE-2020-14367...

CVE-2020-14367

A flaw was found in chrony when creating the PID file under the /var/run/chrony folder. The file is created during chronyd startup while still running as the root user, and when it's opened for writing, chronyd does not check for an existing symbolic link with the same file name. This flaw allows...

CVE-2020-15702

TOCTOU Race Condition vulnerability in apport allows a local attacker to escalate privileges and execute arbitrary code. An attacker may exit the crashed process and exploit PID recycling to spawn a root process with the same PID as the crashed process, which can then be used to escalate...

CVE-2020-15702 TOCTOU in apport

TOCTOU Race Condition vulnerability in apport allows a local attacker to escalate privileges and execute arbitrary code. An attacker may exit the crashed process and exploit PID recycling to spawn a root process with the same PID as the crashed process, which can then be used to escalate...

CVE-2020-15702

CVE-2020-15702 describes a TOCTOU race condition in the Apport component of Ubuntu. The vulnerability allows a local attacker to escalate privileges and potentially execute arbitrary code by exploiting PID recycling after a crash, enabling a root process to inherit the crashed process’ PID. Affec...

According to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - In the Linux kernel 5.4.0-rc2, there is a use-after-free read in the blkaddtrace function in kernel/trace/blktrace.c which is use...

Unspecified Vulnerability in F-Secure SAFE (CNVD-2021-25666)

F-Secure SAFE is a suite of antivirus software from the Finnish company F-Secure. A security vulnerability exists in F-Secure SAFE version 17.7 macOS, which stems from the XPC service's use of a PID to identify the connecting client, and can be exploited by an attacker to execute commands on the...

CVE-2020-14977

An issue was discovered in F-Secure SAFE 17.7 on macOS. The XPC services use the PID to identify the connecting client, which allows an attacker to perform a PID reuse attack and connect to a privileged XPC service, and execute privileged commands on the system. NOTE: the attacker needs to execut...

CVE-2020-14977

The CVE affects F-Secure SAFE 17.7 on macOS. The vulnerability arises because XPC services identify connecting clients by PID, enabling a PID reuse attack that lets an attacker connect to a privileged XPC service and execute privileged commands, provided the attacker already compromised the machi...
