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 attacker to manipulate file paths and access unauthorized data. The core issue stems from insufficient validation of file path lengths during temporary file operations.

The remote SUSE Linux SLES16 / SLES_SAP16 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:20032-1 advisory.

    Update to version 2.84.4.

    Security issues fixed:

    - CVE-2025-14512: integer overflow in the GIO `escape_byte_string()` function when processing malicious     files or remote       filesystem attribute values can lead to denial-of-service (bsc#1254878).
    - CVE-2025-14087: buffer underflow in the GVariant parser `bytestring_parse()` and `string_parse()`     functions when       processing attacker-influenced data may lead to crash or code execution (bsc#1254662).
    - CVE-2025-13601: heap-based buffer overflow in the `g_escape_uri_string()` function when processing     strings with a       large number of unacceptable characters may lead to crash or code execution (bsc#1254297).
    - CVE-2025-7039: integer overflow when creating temporary files may lead to an out-of-bounds memory access     that can be       used for path traversal or exposure of sensitive content in a temporary file (bsc#1249055).

    Other issues fixed and changes:

    - Fix GFile leak in `g_local_file_set_display_name` during error handling.
    - Fix incorrect output parameter handling in closure helper of `g_settings_bind_with_mapping_closures`.
    - `gfileutils`: fix computation of temporary file name.
    - Fix GFile leak in  `g_local_file_set_display_name()`.
    - `gthreadpool`: catch `pool_spawner` creation failure.
    - `gio/filenamecompleter`: fix leaks.
    - `gfilenamecompleter`: fix `g_object_unref()` of undefined value.

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 / 25.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7942-1 advisory.

    It was discovered that GLib incorrectly handled escaping URI strings. An attacker could use this issue to     cause GLib to crash, resulting in a denial of service, or possibly execute arbitrary code.
    (CVE-2025-13601)

    It was discovered that GLib incorrectly parsed certain GVariants. An attacker could use this issue to     cause GLib to crash, resulting in a denial of service, or possibly execute arbitrary code.
    (CVE-2025-14087)

    It was discovered that GLib incorrectly parsed certain long invalid ISO 8601 timestamps. An attacker could     possibly use this issue to cause GLib to crash, resulting in a denial of service. This issue only affected     Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2025-3360)

    Multiple issues were found in GLib, a general-purpose, portable utility     library, that could lead to denial of service, memory corruption or     potentially arbitrary code execution if maliciously crafted data is     processed.

    For Debian 11 bullseye, these problems have been fixed in version     2.66.8-1+deb11u7.

    We recommend that you upgrade your glib2.0 packages.
