The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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)

Note that Nessus relies on the presence of the package as reported by the vendor.

    -------------------------------------------------------------------------

    Package        : glib2.0     Version        : 2.66.8-1+deb11u8     CVE ID         : CVE-2026-0988 CVE-2026-1484 CVE-2026-1485 CVE-2026-1489     Debian Bug     : 1125752 1126549 1126550 1126551

    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.

    CVE-2026-0988

        Codean Labs found 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-2026-1484

        treeplus with additional thanks to Sovereign Tech Resilience program of the         Sovereign Tech Agency 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-2026-1485

        treeplus with additonal thanks to Sovereign Tech Resilience program of the         Sovereign Tech Agency found a flaw 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-2026-1489

        treeplus with additional thanks to Sovereign Tech Resilience program of the         Sovereign Tech Agency found a flaw n 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.

    For Debian 11 bullseye, these problems have been fixed in version     2.66.8-1+deb11u8.

    We recommend that you upgrade your glib2.0 packages.
