In GNOME GLib 2.56.1, g_markup_parse_context_end_parse in gmarkup.c has a NULL pointer dereference. GNOME GLib 2.56.1 has an out-of-bounds read vulnerability in g_markup_parse_context_parse in gmarkup.c, related to utf8_str. The keyfile settings backend in GNOME GLib before 2.60.0 creates directories using g_file_make_directory_with_parents and files using g_file_replace_contents . Consequently, it does not properly restrict directory permissions. Instead, for directories, 0777 permissions are used; for files, default file permissions are used. This is similar to CVE-2019-12450. An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace is used with G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also creates the target of the symlink as an empty file, which could conceivably have security relevance if the symlink is attacker-controlled. A flaw was found in glib before version 2.63.6. Due to random charset alias, pkexec can leak content from files owned by privileged users to unprivileged ones under the right condition. The upstream bug report describes this issue as follows:A vulnerability was found in GLib2.0, where DoS caused by handling a malicious text-form variant which is structured to cause looping superlinear to its text size. Applications are at risk if they parse untrusted text-form variants.
