Vulnerabilities 7

High 7.3
Glib: off-by-one error in glib/gkeyfile.c via "g_key_file_get_locale_string_list"
A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list function in the gkeyfile.c file when loading a key file with an empty value. This flaw can cause an out-of-bounds access of 1 byte or a denial of service when the…

Glib: buffer over-read in glib/gvariant-serialiser.c via gvs_tuple_is_normal()
A flaw was found in GLib. An off-by-one error can occur in the gvs_tuple_is_normal function in the glib/gvariant-serialiser.c file when doing an alignment padding check because the bounds check uses > instead of >=, causing an out-of-bounds read of only 1 byt…

Medium 6.5
Glib: out-of-bounds read in glib/gdatetime.c:g_date_time_get_ymd via invalid gdatetime
A flaw was found in GLib. An out-of-bounds read of only 2 bytes can occur in the g_date_time_get_ymd function in the glib/gdatetime.c file when an invalid GDateTime object produced by the g_date_time_add_full function is processed. This flaw can corrupt the d…

Medium 6.5
Glib: buffer over-read in g_regex_replace() via glib/gregex.c:string_append() and g_utf8_next_char()
A flaw was found in GLib. A buffer over-read can occur in the g_regex_replace function when used with the `G_REGEX_RAW` compile flag and case-change replacement escapes because the string_append function processes matched substrings using UTF-8 functions that…
-
Medium 6.5
Glib: buffer over-read in glib/giochannel.c via "g_io_channel_read_line_backend"
A flaw was found in GLib. A buffer over-read can occur in g_io_channel_read_line_backend() in the giochannel.c file when a custom line terminator with a length greater than one is set, causing memcmp to read past the GString buffer. This vulnerability can cau…
-
Medium 5.9
Glib: path traversal in glib/gio/gdbusauthmechanismsha1.c via keyring_lookup_entry and mechanism_client_data_receive
A flaw was found in GLib. The D-Bus client-side implementation of the DBUS_COOKIE_SHA1 SASL authentication mechanism does not validate the cookie_context parameter received from the server. A malicious D-Bus server can supply a cookie_context containing path …

Medium 5.3
Gdbusserver: glib2: gdbusserver pre-authentication dos via unbounded sasl line buffering
A denial-of-service and resource exhaustion vulnerability exists within the `GDBus` component of GLib. The `gdbusauth` authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote att…
