High Nessus Plugin ID 137363

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:2522 advisory.

- kernel: double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (CVE-2017-18595)

- kernel: usb: missing size check in the
__usb_get_extra_descriptor() leading to DoS (CVE-2018-20169)

- kernel: denial of service via ioctl call in network tun handling (CVE-2018-7191)

- Kernel: net: using kernel space address bits to derive IP ID may potentially break KASLR (CVE-2019-10639)

- kernel: unchecked kstrdup of fwstr in drm_load_edid_firmware leads to denial of service (CVE-2019-12382)

- kernel: use-after-free in arch/x86/lib/insn-eval.c (CVE-2019-13233)

- kernel: integer overflow and OOB read in drivers/block/floppy.c (CVE-2019-14283)

- kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c leads to denial of service (CVE-2019-15916)

- kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c (CVE-2019-19768)

- kernel: perf_event_open() and execve() race in setuid programs allows a data leak (CVE-2019-3901)

- kernel: brcmfmac frame validation bypass (CVE-2019-9503)

- Kernel: NetLabel: null pointer dereference while receiving CIPSO packet with null category may cause kernel panic (CVE-2020-10711)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
