A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via an integer overflow in GLib's GIO (GLib Input/Output) escape_byte_string() function when processing malicious file or remote filesystem attribute values.

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

    A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap     corruption, leading to a denial of service or potential code execution via a buffer-underflow in the     GVariant parser when processing maliciously crafted input strings.(CVE-2025-14087)

    A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in     the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable     characters (which would need escaping), the calculation of the length of the escaped string could     overflow, leading to a potential write off the end of the newly allocated string.(CVE-2025-13601)

    A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via     an integer overflow in GLib's GIO (GLib Input/Output) escape_byte_string() function when processing     malicious file or remote filesystem attribute values.(CVE-2025-14512)

    A flaw was found in glib. Missing validation of offset and count parameters in the     g_buffered_input_stream_peek() function can lead to an integer overflow during length calculation. When     specially crafted values are provided, this overflow results in an incorrect size being passed to     memcpy(), triggering a buffer overflow. This can cause application crashes, leading to a Denial of Service     (DoS).(CVE-2026-0988)

    A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap     corruption, leading to a denial of service or potential code execution via a buffer-underflow in the     GVariant parser when processing maliciously crafted input strings.(CVE-2025-14087)

    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.(CVE-2025-7039)

    A flaw was found in GLib, which is vulnerable to an integer overflow in the g_string_insert_unichar()     function. When the position at which to insert the character is large, the position will overflow, leading     to a buffer underwrite.(CVE-2025-4373)

    A flaw was found in GLib. An integer overflow and buffer under-read occur when parsing a long invalid ISO     8601 timestamp with the g_date_time_new_from_iso8601() function.(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.

    For the detailed security status of glib2.0 please refer to     its security tracker page at:
    https://security-tracker.debian.org/tracker/glib2.0
