The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2019:3553 advisory.

  - WebKitGTK and WPE WebKit prior to version 2.24.1 failed to properly apply configured HTTP proxy settings     when downloading livestream video (HLS, DASH, or Smooth Streaming), an error resulting in deanonymization.
    This issue was corrected by changing the way livestreams are downloaded. (CVE-2019-11070)

  - The tiff_document_render() and tiff_document_get_thumbnail() functions in the TIFF document backend in     GNOME Evince through 3.32.0 did not handle errors from TIFFReadRGBAImageOriented(), leading to     uninitialized memory use when processing certain TIFF image files. (CVE-2019-11459)

  - daemon/gvfsdaemon.c in gvfsd from GNOME gvfs before 1.38.3, 1.40.x before 1.40.2, and 1.41.x before 1.41.3     opened a private D-Bus server socket without configuring an authorization rule. A local attacker could     connect to this server socket and issue D-Bus method calls. (Note that the server socket only accepts a     single connection, so the attacker would have to discover the server and connect to the socket before its     owner does.) (CVE-2019-12795)

  - It was discovered that the gnome-shell lock screen since version 3.15.91 did not properly restrict all     contextual actions. An attacker with physical access to a locked workstation could invoke certain keyboard     shortcuts, and potentially other actions. (CVE-2019-3820)

  - Multiple memory corruption issues were addressed with improved memory handling. This issue is fixed in iOS     12.3, macOS Mojave 10.14.5, tvOS 12.3, Safari 12.1.1, iTunes for Windows 12.9.5, iCloud for Windows 7.12.

  - WebKitGTK and WPE WebKit prior to version 2.24.1 are vulnerable to address bar spoofing upon certain     JavaScript redirections. An attacker could cause malicious web content to be displayed as if for a trusted     URI. This is similar to the CVE-2018-8383 issue in Microsoft Edge. (CVE-2019-6251)

  - A type confusion issue was addressed with improved memory handling. This issue is fixed in iOS 12.2, tvOS     12.2, watchOS 5.2, Safari 12.1, iTunes 12.9.4 for Windows, iCloud for Windows 7.11. Processing maliciously     crafted web content may lead to arbitrary code execution. (CVE-2019-8506)

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

Simon McVittie discovered a flaw in gvfs, the Gnome Virtual File System. The gvfsd daemon opened a private D-Bus server socket without configuring an authorization rule. A local attacker could connect to this server socket and issue D-Bus method calls.

(Note that the server socket only accepts a single connection, so the attacker would have to discover the server and connect to the socket before its owner does.)

For Debian 8 'Jessie', this problem has been fixed in version 1.22.2-1+deb8u1.

We recommend that you upgrade your gvfs packages.

According to the version of the gvfs packages installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - daemon/gvfsdaemon.c in gvfsd from GNOME gvfs before     1.38.3, 1.40.x before 1.40.2, and 1.41.x before 1.41.3     opened a private D-Bus server socket without     configuring an authorization rule. A local attacker     could connect to this server socket and issue D-Bus     method calls. (Note that the server socket only accepts     a single connection, so the attacker would have to     discover the server and connect to the socket before     its owner does.)(CVE-2019-12795)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - daemon/gvfsdaemon.c in gvfsd from GNOME gvfs before 1.38.3, 1.40.x before 1.40.2, and 1.41.x before 1.41.3     opened a private D-Bus server socket without configuring an authorization rule. A local attacker could     connect to this server socket and issue D-Bus method calls. (Note that the server socket only accepts a     single connection, so the attacker would have to discover the server and connect to the socket before its     owner does.) (CVE-2019-12795)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2022:0108 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2018-20337:
    There is a stack-based buffer overflow in the parse_makernote function of dcraw_common.cpp in LibRaw     0.19.1. Crafted input will lead to a denial of service or possibly unspecified other impact.

    CVE-2019-3825:
    A vulnerability was discovered in gdm before 3.31.4. When timed login is enabled in configuration, an     attacker could bypass the lock screen by selecting the timed login user and waiting for the timer to     expire, at which time they would gain access to the logged-in user's session.

    CVE-2019-3827:
    An incorrect permission check in the admin backend in gvfs before version 1.39.4 was found that allows     reading and modify arbitrary files by privileged users without asking for password when no authentication     agent is running. This vulnerability can be exploited by malicious programs running under privileges of     users belonging to the wheel group to further escalate its privileges by modifying system files without     user's knowledge. Successful exploitation requires uncommon system configuration.

    CVE-2019-12447:
    An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles file     ownership because setfsuid is not used.

    CVE-2019-12448:
    An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c has race conditions     because the admin backend doesn't implement query_info_on_read/write.

    CVE-2019-12449:
    An issue was discovered in GNOME gvfs 1.29.4 through 1.41.2. daemon/gvfsbackendadmin.c mishandles a file's     user and group ownership during move (and copy with G_FILE_COPY_ALL_METADATA) operations from admin:// to     file:// URIs, because root privileges are unavailable.

    CVE-2019-12795:
    daemon/gvfsdaemon.c in gvfsd from GNOME gvfs before 1.38.3, 1.40.x before 1.40.2, and 1.41.x before 1.41.3     opened a private D-Bus server socket without configuring an authorization rule. A local attacker could     connect to this server socket and issue D-Bus method calls.(Note that the server socket only accepts a     single connection, so the attacker would have to discover the server and connect to the socket before its     owner does.)

    CVE-2019-15690:
    ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when     announcing a new security problem. When the candidate has been publicized, the details for this candidate     will be provided.

    CVE-2019-20839:
    libvncclient/sockets.c in LibVNCServer before 0.9.13 has a buffer overflow via a long socket filename.

    CVE-2020-14397:
    An issue was discovered in LibVNCServer before 0.9.13. libvncserver/rfbregion.c has a NULL pointer     dereference.

    CVE-2020-14405:
    An issue was discovered in LibVNCServer before 0.9.13. libvncclient/rfbproto.c does not limit TextChat     size.

    CVE-2020-15503:
    LibRaw before 0.20-RC1 lacks a thumbnail size range check. This affects decoders/unpack_thumb.cpp,     postprocessing/mem_image.cpp, and utils/thumb_utils.cpp. For example,     malloc(sizeof(libraw_processed_image_t)+T.tlength) occurs without validating T.tlength.

    CVE-2020-25708:
    A divide by zero issue was found to occur in libvncserver-0.9.12. A malicious client could use this flaw     to send a specially crafted message that, when processed by the VNC server, would lead to a floating point     exception, resulting in a denial of service.
