if an executable was replaced after a crash. A local attacker could
possibly use this issue to execute arbitrary code as the root user.
(CVE-2021-3899)

Gerrit Venema discovered that Apport incorrectly handled connections to
Apport sockets inside containers. A local attacker could possibly use this
issue to connect to arbitrary sockets as the root user. (CVE-2022-1242)

Gerrit Venema discovered that Apport incorrectly handled user settings
files. A local attacker could possibly use this issue to cause Apport to
consume resources, leading to a denial of service. (CVE-2022-28652)

Gerrit Venema discovered that Apport did not limit the amount of logging
from D-Bus connections. A local attacker could possibly use this issue to
fill up the Apport log file, leading to a denial of service.
(CVE-2022-28654)

Gerrit Venema discovered that Apport did not filter D-Bus connection
strings. A local attacker could possibly use this issue to cause Apport to
make arbitrary network connections. (CVE-2022-28655)

Gerrit Venema discovered that Apport did not limit the amount of memory
being consumed during D-Bus connections. A local attacker could possibly
use this issue to cause Apport to consume memory, leading to a denial of
service. (CVE-2022-28656)

Gerrit Venema discovered that Apport did not disable the python crash
handler before chrooting into a container. A local attacker could possibly
use this issue to execute arbitrary code. (CVE-2022-28657)

Gerrit Venema discovered that Apport incorrectly handled filename argument
whitespace. A local attacker could possibly use this issue to spoof
arguments to the Apport daemon. (CVE-2022-28658)");
