(CVE-2020-11098)\n\n - In FreeRDP before version 2.1.2, there is an out of bounds read in\n license_read_new_or_upgrade_license_packet. A manipulated license packet can lead to out of bound reads to\n an internal buffer. This is fixed in version 2.1.2. (CVE-2020-11099)\n\n - In FreeRDP less than or equal to 2.1.2, an integer overflow exists due to missing input sanitation in\n rdpegfx channel. All FreeRDP clients are affected. The input rectangles from the server are not checked\n against local surface coordinates and blindly accepted. A malicious server can send data that will crash\n the client later on (invalid length arguments to a `memcpy`) This has been fixed in 2.2.0. As a\n workaround, stop using command line arguments /gfx, /gfx-h264 and /network:auto (CVE-2020-15103)\n\nNote that Nessus has not tested for this issue but has instead relied only on the application's self-reported version\nnumber.\");\n script_set_attribute(attribute:\"see_also\", value:\"https://errata.almalinux.org/8/ALSA-2021-1849.html\");\n script_set_attribute(attribute:\"solution\", value:\n\"Update the affected freerdp-devel package.\");\n script_set_cvss_base_vector(\"CVSS2#AV:N/AC:L/Au:N/C:P/I:N/A:P\");\n script_set_cvss_temporal_vector(\"CVSS2#E:U/RL:OF/RC:C\");\n script_set_cvss3_base_vector(\"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L\");\n script_set_cvss3_temporal_vector(\"CVSS:3.0/E:U/RL:O/RC:C\");\n script_set_attribute(attribute:\"cvss_score_source\", value:\"CVE-2020-4033\");\n\n script_set_attribute(attribute:\"exploitability_ease\", value:\"No known exploits are available\");\n script_set_attribute(attribute:\"exploit_available\", value:\"false\");\n\n script_set_attribute(attribute:\"vuln_publication_date\", value:\"2020/06/22\");\n script_set_attribute(attribute:\"patch_publication_date\", value:\"2021/05/18\");\n script_set_attribute(attribute:\"plugin_publication_date\", value:\"2022/02/09\");\n\n script_set_attribute(attribute:\"plugin_type\", value:\"local\");\n script_set_attribute(attribute:\"cpe\", value:\"p-cpe:/a:alma:linux:freerdp-devel\");\n script_set_attribute(attribute:\"cpe\", value:\"cpe:/o:alma:linux:8\");\n script_end_attributes();\n\n script_category(ACT_GATHER_INFO);\n script_family(english:\"Alma Linux Local Security Checks\");\n\n script_copyright(english:\"This script is Copyright (C) 2022 and is owned by Tenable, Inc. or an Affiliate thereof.\");\n\n script_dependencies(\"ssh_get_info.nasl\");\n script_require_keys(\"Host/local_checks_enabled\", \"Host/AlmaLinux/release\", \"Host/AlmaLinux/rpm-list\", \"Host/cpu\");\n\n exit(0);\n}\n\n\ninclude('audit.inc');\ninclude('global_settings.inc');\ninclude('misc_func.inc');\ninclude('rpm.inc');\n\nif (!get_kb_item('Host/local_checks_enabled')) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED);\nvar release = get_kb_item('Host/AlmaLinux/release');\nif (isnull(release) || 'AlmaLinux' >!< release) audit(AUDIT_OS_NOT, 'AlmaLinux');\nvar os_ver = pregmatch(pattern: \"AlmaLinux release ([0-9]+(\\.[0-9]+)?)\", string:release);\nif (isnull(os_ver)) audit(AUDIT_UNKNOWN_APP_VER, 'AlmaLinux');\nvar os_ver = os_ver[1];\nif (!
