low Nessus Plugin ID 210813

Synopsis

The remote Red Hat host is missing a security update for bpftrace.

Description

The remote Redhat Enterprise Linux 9 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2024:9188 advisory.

 BPFtrace is a high-level tracing language for Linux enhanced Berkeley Packet Filter (eBPF) available in recent Linux kernels (4.x). BPFtrace uses LLVM as a backend to compile scripts to BPF-bytecode and makes use of BCC for interacting with the Linux BPF system, as well as existing Linux tracing capabilities:
 kernel dynamic tracing (kprobes), user-level dynamic tracing (uprobes), and tracepoints. The BPFtrace language is inspired by awk and C, and predecessor tracers such as DTrace and SystemTap

 Security Fix(es):

 * bpftrace: unprivileged users can force loading of compromised linux headers (CVE-2024-2313)
