    Package        : libsmpp34
    Version        : 1.14.1-3+deb12u1
    CVE ID         : CVE-2026-75895


    An issue has been found in libsmpp34, a library for Open PDU SMPP
    packaging and unpackaging. The issue is related to an out of bound read
    while processing attacker controlled SMPP PDUs, which could lead to
    memory corruption.

    The only way to avoid this issue is to update the software.


    For Debian 12 bookworm, this problem has been fixed in version
    1.14.1-3+deb12u1.

    We recommend that you upgrade your libsmpp34 packages.

    For the detailed security status of libsmpp34 please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/libsmpp34

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
