[NEW] [high] Red Hat Enterprise Linux (mrtg, kbd, urwid): Multiple vulnerabilities
An attacker can exploit multiple vulnerabilities in Red Hat Enterprise Linux to elevate privileges, execute arbitrary code, manipulate or disclose data, and trigger a denial-of-service condition.
CSIRTS triage
- What
- Multiple vulnerabilities in RHEL components (mrtg, kbd, urwid) enable privilege escalation, arbitrary code execution, data manipulation or disclosure, and denial of service.
- Who is affected
- Red Hat Enterprise Linux systems with affected mrtg, kbd, or urwid packages.
- Urgency
- High: severity rated high; privilege escalation capabilities require urgent patching.
- Action
- Apply Red Hat security updates for affected packages via yum or package manager.
