Canonical Apport: vulnerabilidades y CVE

Path traversal in apport-unpack in Canonical Apport before 2.36.0, 2.34.2, and 2.28.4 on Linux allows an attacker to create or overwrite arbitrary files with the privileges of the executing user via an attacker…

It was discovered that process_crash() in data/apport in Canonical's Apport crash reporting tool may create crash files with incorrect group ownership, possibly exposing crash information beyond expected or intended…

Race condition in Canonical apport up to and including 2.32.0 allows a local attacker to leak sensitive information via PID-reuse by leveraging namespaces. When handling a crash, the function…

gdbus setgid privilege escalation

Users can consume unlimited disk space in /var/crash

Apport can be tricked into connecting to arbitrary sockets as the root user

There is a race condition in the 'replaced executable' detection that, with the correct local configuration, allow an attacker to execute arbitrary code as root.

A privilege escalation attack was found in apport-cli 2.26.0 and earlier which is similar to CVE-2023-26604. If a system is specially configured to allow unprivileged users to run sudo apport-cli, less is configured as…

It was discovered that the get_pid_info() function in data/apport did not properly parse the /proc/pid/status file from the kernel.

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…

An unhandled exception in check_ignored() in apport/report.py can be exploited by a local attacker to cause a denial of service. If the mtime attribute is a string value in apport-ignore.xml, it will trigger an…

Any Python module in sys.path can be imported if the command line of the process triggering the coredump is Python and the first argument is -m in Apport before 2.19.2 function _python_module_path.
