CVE-2026-1489 (GCVE-0-2026-1489)

Vulnerability from cvelistv5 – Published: 2026-01-27 14:26 – Updated: 2026-06-02 13:00

Title

Glib: glib: memory corruption via integer overflow in unicode case conversion

Summary

A flaw was found in GLib. 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.

Summary

glib2 security update

Details

GLib is a bundle of three (formerly five) low-level system libraries written in C and developed mainly by GNOME. 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.

Security Fix(es):

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 that process untrusted or extremely large Base64 input using GLib may crash or behave unpredictably.(CVE-2026-1484)

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 memory access. Exploitation requires a local user to install or process a specially crafted treemagic file, which can lead to local denial of service or application instability.(CVE-2026-1485)

Severity

5.4 (Medium)

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.

OESA-2026-1397 (CVE-2026-0988)

Vulnerability from osv_openeuler – Published: 2026-02-13 11:10 – Updated: 2026-08-06 11:10 – Source website

Summary

glib2 security update

Details

Security Fix(es):

Integer Overflow vulnerability in the g_buffered_input_stream_peek() function of the GLib library. The issue is caused by missing validation of the offset and count parameters, leading to an unsafe arithmetic operation during length calculation. When specially crafted values are provided, the offset + count computation may overflow, resulting in an incorrect size being passed to memcpy(). This can trigger a heap or stack buffer overflow and lead to a segmentation fault. Exploitation is subject to strict preconditions and primarily impacts availability by causing application crashes.(CVE-2026-0988)

Severity

5.4 (Medium)

Summary

glib2 security update

Details

Security Fix(es):

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 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)

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 date output and potentially cause logic errors that may lead to a denial of service.(CVE-2026-58011)

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 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)

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 crosses a page boundary.(CVE-2026-58014)

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 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)

A 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)

Severity

9.1 (Critical)
