EulerOS 2.0 SP12 : glib2 (EulerOS-SA-2026-4405)

high Nessus Plugin ID 376667

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the glib2 packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

A denial-of-service and resource exhaustion vulnerability exists within the `GDBus` component of GLib. The `gdbusauth` authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input validation by sending excessively long streams of data, causing the application to consume massive amounts of system memory and CPU, potentially leading to a crash or system hang.(CVE-2026-15588)

A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in
_xdg_mime_magic_parse_magic_line() in the xdgmimemagic.c file on little-endian systems when an attacker- controlled MIME magic file in a user-writable XDG data location (e.g., in the $XDG_DATA_HOME/mime/magic path) is parsed by an application performing MIME type detection (e.g., via g_content_type_guess()). When performing byte-swap, incorrect pointer arithmetic on the write side causes an out-of-bounds write of 2 bytes, resulting in an application crash or memory corruption.(CVE-2026-16118)

Tenable has extracted the preceding description block directly from the EulerOS glib2 security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected glib2 packages.
