   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 out-of-bounds access...

7. CVE-2026-58013 Glib: buffer over-read in glib/giochannel.c via "g_io_channel_read_line_backend"

   Published 2026-06-30

   High·CVSS 8.2 EPSS 0.71%

   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 cause a minor informatio...

8. CVE-2026-58012 Glib: buffer over-read in g_regex_replace() via glib/gregex.c:string_append() and g_utf8_next_char()

    Published 2026-01-27

    Low·CVSS 2.8 EPSS 0.16%

    A flaw was found in Glib's content type parsing logic. This buffer underflow vulnerability occurs because the length of a header line is stored in a signed integer, which can lead to integer wraparound for very large inputs. This results in pointer underflow and out-of-bounds mem...

14. CVE-2026-1484 Glib: integer overflow leading to buffer underflow and out-of-bounds write in glib g_base64_encode()

    Published 2026-01-27

    Medium·CVSS 4.2 EPSS 0.34%

    A flaw was found in the GLib Base64 encoding routine when processing very large input data. Due to incorrect use of integer types during length calculation, the library may miscalculate buffer boundaries. This can cause memory writes outside the allocated buffer. Applications tha...

15. CVE-2026-0988 Glib: glib: denial of service via integer overflow in g_buffered_input_stream_peek()

    Published 2026-01-21

    Low·CVSS 3.7 EPSS 0.43%

    A flaw was found in glib. Missing validation of offset and count parameters in the g_buffered_input_stream_peek() function can lead to an integer overflow during length calculation. When specially crafted values are provided, this overflow results in an incorrect size being passe...

    Published 2025-12-10

    Critical·CVSS 9.8 EPSS 0.89%

    A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings.

19. CVE-2025-13601 Glib: integer overflow in in g_escape_uri_string()

    Published 2025-11-26

    High·CVSS 7.7 EPSS 0.35%

    A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length...

20. CVE-2025-7039 Glib: buffer under-read on glib through glib/gfileutils.c via get_tmp_file()

    Published 2025-09-03

    Low·CVSS 3.7 EPSS 0.43%

    A flaw was found in glib. An integer overflow during temporary file creation leads to an out-of-bounds memory access, allowing an attacker to potentially perform path traversal or access private temporary file content by creating symbolic links. This vulnerability allows a local...

21. CVE-2025-4056 Glib: glib crash after long command line

    Published 2025-07-28

    High·CVSS 7.5 EPSS 0.54%

    Published 2025-06-13

    High·CVSS 7.5 EPSS 0.54%

    A flaw was found in how GLib’s GString manages memory when adding data to strings. If a string is already very large, combining it with more input can cause a hidden overflow in the size calculation. This makes the system think it has enough memory when it doesn’t. As a result, d...

23. CVE-2025-4373 Glib: buffer underflow on glib through glib/gstring.c via function g_string_insert_unichar

    Published 2025-05-06

    Medium·CVSS 4.8 EPSS 0.65%

    A flaw was found in GLib, which is vulnerable to an integer overflow in the g_string_insert_unichar() function. When the position at which to insert the character is large, the position will overflow, leading to a buffer underwrite.

24. DLA-4128-1 glib2.0 - security update

    Published 2025-04-13

    Unknown

25. CVE-2025-3360 Glibc: glib prior to 2.82.5 is vulnerable to integer overflow and buffer under-read when parsing a very long invalid iso 8601 timestamp with g_date_time_new_from_iso8601().

    Published 2025-04-07
