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.

Solution

Update the affected packages.
