    Package        : needrestart
    Version        : 3.5-4+deb11u4
    CVE ID         : CVE-2024-11003 CVE-2024-48990 CVE-2024-48991 CVE-2024-48992

    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).

    Details can be found in the Qualys advisory at
    https://www.qualys.com/2024/11/19/needrestart/needrestart.txt

    For Debian 11 bullseye, these problems have been fixed in version
    3.5-4+deb11u4.

    We recommend that you upgrade your needrestart packages.
