GLib's code was separated from GTK, so it can be used by software other than GNOME and has been developed in parallel ever since.\r\n\r\nSecurity Fix(es):\n\nA 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 byte. This issue can cause a minor information disclosure of 1 byte and a denial of service when the out-of-bounds read crosses a page boundary.(CVE-2026-58010)\n\nA 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 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 <node> element nested within other elements like <method>, <signal>, <property> or <arg>. This issue can cause an unsigned integer overflow and lead to an out-of-bounds read, resulting in a denial of service.(CVE-2026-58016)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP4","name":"glib2","purl":"pkg:rpm/openEuler/glib2&distro=openEuler-24.03-LTS-SP4"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.78.3-17.oe2403sp4"}]}],"ecosystem_specific":{"aarch64":["glib2-2.78.3-17.oe2403sp4.aarch64.rpm","glib2-debuginfo-2.78.3-17.oe2403sp4.aarch64.rpm","glib2-debugsource-2.78.3-17.oe2403sp4.aarch64.rpm","glib2-devel-2.78.3-17.oe2403sp4.aarch64.rpm","glib2-static-2.78.3-17.oe2403sp4.aarch64.rpm","glib2-tests-2.78.3-17.oe2403sp4.aarch64.rpm"],"noarch":["glib2-help-2.78.3-17.oe2403sp4.noarch.rpm"],"src":["glib2-2.78.3-17.oe2403sp4.src.rpm"],"x86_64":["glib2-2.78.3-17.oe2403sp4.x86_64.rpm","glib2-debuginfo-2.78.3-17.oe2403sp4.x86_64.rpm","glib2-debugsource-2.78.3-17.oe2403sp4.x86_64.rpm","glib2-devel-2.78.3-17.oe2403sp4.x86_64.rpm","glib2-static-2.78.3-17.oe2403sp4.x86_64.rpm","glib2-tests-2.78.3-17.oe2403sp4.x86_64.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-3112"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58010"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58011"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58012"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58014"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58015"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-58016"}],"database_specific":{"severity":"Critical"}}
