possibly use this issue to execute arbitrary code as root.
(CVE-2024-11003)

parsed perl code. This could allow a local attacker to execute arbitrary
shell commands. (CVE-2024-10224)

environment variable to spawn a new Python interpreter. A local attacker
could possibly use this issue to execute arbitrary code as root.
(CVE-2024-48990)

Qualys discovered that needrestart incorrectly checked the path to the
Python interpreter. A local attacker could possibly use this issue to win
a race condition and execute arbitrary code as root. (CVE-2024-48991)
