The Qualys Threat Research Unit discovered several local privilege
escalation vulnerabilities in needrestart, a utility to check which
daemons need to be restarted after library upgrades. A local attacker
can execute arbitrary code as root by tricking needrestart into running
the Python interpreter with an attacker-controlled PYTHONPATH
environment variable (CVE-2024-48990) or running the Ruby interpreter
with an attacker-controlled RUBYLIB environment variable
(CVE-2024-48992). Additionally a local attacker can trick needrestart
into running a fake Python interpreter (CVE-2024-48991) or cause
needrestart to call the Perl module Module::ScanDeps with
attacker-controlled files (CVE-2024-11003).
