  script_tag(name:"vuldetect", value:"Checks if a vulnerable package version is present on the target host.");

  script_tag(name:"insight", value:"This update is based on the upstream 5.6.14 kernel and fixes at least
the following security issues:

A NULL pointer dereference flaw was found in the Linux kernel's SELinux
subsystem in versions before 5.7. This flaw occurs while importing the
Commercial IP Security Option (CIPSO) protocol's category bitmap into
the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine.
While processing the CIPSO restricted bitmap tag in the
'cipso_v4_parsetag_rbm' routine, it sets the security attribute to
indicate that the category bitmap is present, even if it has not been
allocated. This issue leads to a NULL pointer dereference issue while
importing the same category bitmap into SELinux. This flaw allows a
remote network user to crash the system kernel, resulting in a denial
of service (CVE-2020-10711).

An issue was discovered in the Linux kernel through 5.6.11. sg_write
lacks an sg_remove_request call in a certain failure case
(CVE-2020-12770).

gadget_dev_desc_UDC_store in drivers/usb/gadget/configfs.c in the Linux
kernel through 5.6.13 relies on kstrdup without considering the
possibility of an internal '\0' value, which allows attackers to trigger
an out-of-bounds read (CVE-2020-13143).

Other fixes in this update:
- KVM: x86: only do L1TF workaround on affected processors (this now
 correctly excludes non-affected AMD Ryzen and EPYC processors)
- add Amd Renoir detection to amd_nb, hwmon (k10temp) and EDAC
- additional fixes to the integrated virtualbox support for better
 interaction with virtualbox.org releases
- ndiswrapper has been updated to 1.63
- wireguard-tools have been updated to 1.0.20200513

For other upstream fixes and changes in this update, see the refenced
changelogs.");
