An integer overflow vulnerability in its Unicode case conversion implementation can lead to memory corruption. By processing specially crafted and extremely large Unicode strings, an attacker could trigger an undersized memory allocation, resulting in out-of-bounds writes.

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 date output and potentially cause logic errors that may lead to a denial of service.(CVE-2026-58011)\n\nA 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 assume valid UTF-8 input, even when the string is treated as raw bytes. This vulnerability can cause a minor information disclosure of 1-5 bytes and a denial of service when the buffer over-read crosses a page boundary.(CVE-2026-58012)\n\nA 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 crosses a page boundary.(CVE-2026-58014)\n\nA 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 traversal sequences, causing the client to read an arbitrary file and exfiltrate sensitive data by verifying guessed file contents against a generated hash.(CVE-2026-58015)\n\nA flaw was found in GLib. A state confusion issue exists in g_dbus_node_info_new_for_xml() in the gio/gdbusintrospection.c file when processing malformed D-Bus introspection XML, specifically with a \u0026lt;node\u0026gt; element nested within other elements like \u0026lt;method\u0026gt;, \u0026lt;signal\u0026gt;, \u0026lt;property\u0026gt; or \u0026lt;arg\u0026gt;.

An integer overflow vulnerability in its Unicode case conversion implementation can lead to memory corruption. By processing specially crafted and extremely large Unicode strings, an attacker could trigger an undersized memory allocation, resulting in out-of-bounds writes. This could cause applications utilizing GLib for string conversion to crash or become unstable.","status":"published","published":"2026-01-27T15:15:57Z","modified":"2026-11-05T05:40:51Z","updated_at":"2026-11-05T16:41:24.626116Z"},{"id":"CLSA-2026-1776246056","title":"glib2: Fix of 5 CVEs","description":"- CVE-2026-1489: fix integer overflow in Unicode case conversion functions\n- CVE-2026-1484: fix integer overflow in GLib Base64 encoding\n- CVE-2026-1485: fix buffer underflow in content type treemagic parsing\n- CVE-2026-0988: fix integer overflow in g_buffered_input_stream_peek()\n- CVE-2025-7039: fix integer overflow in temporary file creation","status":"published","published":"2026-04-15T23:18:17Z","modified":"2026-10-21T10:47:29.046209061Z","updated_at":"2026-11-02T15:43:44.009773Z"},{"id":"CLSA-2026-1776329620","title":"glib2: Fix of 6 CVEs","description":"- CVE-2026-1489: fix integer overflow in Unicode case conversion functions\n- CVE-2026-1484: fix integer overflow in GLib Base64 encoding\n- CVE-2025-14512: fix integer overflow in escape_byte_string() for byte\n  strings with many invalid characters\n- CVE-2026-1485: fix buffer underflow in content type treemagic parsing\n- CVE-2026-0988: fix integer overflow in g_buffered_input_stream_peek()\n- CVE-2025-7039: fix integer overflow in temporary file creation","status":"published","published":"2026-04-16T08:53:45Z","modified":"2026-10-21T10:46:21.849680576Z","updated_at":"2026-11-02T15:43:44.009773Z"},{"id":"DLA-4491-1","title":"glib2.0 - security update","status":"published","published":"2026-02-23T00:00:00Z","modified":"2026-02-23T11:30:33.00135Z","updated_at":"2026-11-02T15:46:12.7027Z"},{"id":"openSUSE-SU-2026:10111-1","title":"gio-branding-upstream-2.86.3-3.1 on GA media","description":"These are all security issues fixed in the gio-branding-upstream-2.86.3-3.1 package on the GA media of openSUSE Tumbleweed.","status":"published","published":"2026-01-29T00:00:00Z","modified":"2026-03-23T04:54:28.03998Z","updated_at":"2026-11-02T16:58:38.101535Z"},{"id":"openSUSE-SU-2026:20150-1","title":"Security update for glib2","description":"This update for glib2 fixes the following issues:\n\n- CVE-2026-1485: Fixed buffer underflow and out-of-bounds access due to integer wraparound in content type parsing (bsc#1257354).\n- CVE-2026-1484: Fixed buffer underflow and out-of-bounds access due to miscalculated buffer boundaries in the Base64 encoding routine (bsc#1257355).\n- CVE-2026-1489: Fixed undersized heap allocation followed by out-of-bounds access due to integer overflow in Unicode case conversion (bsc#1257353).\n- CVE-2026-0988: Fixed a potential integer overflow in g_buffered_input_stream_peek (bsc#1257049).\n","status":"published","published":"2026-02-02T12:41:24Z","modified":"2026-03-23T04:54:46.163479Z","updated_at":"2026-11-02T16:58:41.463445Z"},{"id":"ROOT-OS-DEBIAN-12-CVE-2026-1489","title":"CVE-2026-1489 in rootio-glib2.0 - Patched by Root","description":"Root has patched CVE-2026-1489 in the rootio-glib2.0 package for Root:Debian:12.
