Уязвимость функций g_file_make_directory_with_parents, g_file_replace_contents библиотеки Glib, позволяющая нарушителю повысить свои привилегии и получить доступ к файлам

The keyfile settings backend in GNOME GLib (aka glib2.0) before 2.60.0 creates directories using g_file_make_directory_with_parents (kfsb->dir, NULL, NULL) and files using g_file_replace_contents (kfsb->file, contents, length, NULL, FALSE, G_FILE_CREATE_REPLACE_DESTINATION, NULL, NULL, NULL). Consequently, it does not properly restrict directory (and file) permissions. Instead, for directories, 0777 permissions are used; for files, default file permissions are used. This is similar to CVE-2019-12450.

Уязвимость подсистемы UIProcess модулей отображения веб-страниц WebKitGTK+, WebKitGTK, позволяющая нарушителю вызвать отказ в обслуживании или оказать воздействие на конфиденциальность и целостность защищаемой информации

The UIProcess subsystem in WebKit, as used in WebKitGTK through 2.23.90 and WebKitGTK+ through 2.22.6 and other products, does not prevent the script dialog size from exceeding the web view size, which allows remote attackers to cause a denial of service (Buffer Overflow) or possibly have unspecified other impact, related to UIProcess/API/gtk/WebKitScriptDialogGtk.cpp, UIProcess/API/gtk/WebKitScriptDialogImpl.cpp, and UIProcess/API/gtk/WebKitWebViewGtk.cpp, as demonstrated by GNOME Web (aka Epiphany).

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.

GNOME Keyring through 3.28.2 allows local users to retrieve login credentials via a Secret Service API call and the D-Bus interface if the keyring is unlocked, a similar issue to CVE-2008-7320. One perspective is that this occurs because available D-Bus protection mechanisms (involving the busconfig and policy XML elements) are not used. NOTE: the vendor disputes this because, according to the security model, untrusted applications must not be allowed to access the user's session bus socket.

Уязвимость модулей отображения веб-страниц WebKitGTK и WPE WebKit, связанная с недостаточной проверкой входных данных, позволяющая нарушителю проводить спуфинг-атаки

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.

An issue was discovered in gThumb through 3.6.2. There is a double-free vulnerability in the add_themes_from_dir method in dlg-contact-sheet.c because of two successive calls of g_free, each of which frees the same buffer.

Уязвимость функции ldb_wildcard_compare компонента LDAP пакета программ сетевого взаимодействия Samba, позволяющая нарушителю вызвать отказ в обслуживании

A flaw was found in the way an LDAP search expression could crash the shared LDAP server process of a samba AD DC in samba before version 4.10. An authenticated user, having read permissions on the LDAP server, could use this flaw to cause denial of service.
