The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1776246056 advisory.

  - 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. 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 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)

  - 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. (CVE-2026-1489)

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

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20150-1 advisory.

    - CVE-2026-1485: Fixed buffer underflow and out-of-bounds access due to integer wraparound in content type     parsing (bsc#1257354).
    - CVE-2026-1484: Fixed buffer underflow and out-of-bounds access due to miscalculated buffer boundaries in     the Base64 encoding routine (bsc#1257355).
    - CVE-2026-1489: Fixed undersized heap allocation followed by out-of-bounds access due to integer overflow     in Unicode case conversion (bsc#1257353).
    - CVE-2026-0988: Fixed a potential integer overflow in g_buffered_input_stream_peek (bsc#1257049).

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. 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.(CVE-2026-1489)

    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)

    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. 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 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)
