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

    A NULL pointer dereference in the SQLite Session Extension in SQLite 3.53.1 and SQLite trunk builds before
    check-in e807d4e3798efd53 allows an attacker who can supply a malformed changeset blob to cause a denial
    of service. The issue occurs when sqlite3changeset_apply_v3() applies a corrupt changeset and reaches
    sqlite3_value_type() with a NULL sqlite3_value pointer.(CVE-2026-50812)

    An issue in SQLite before Fossil check-in 869a51ae84df allows a local attacker to obtain sensitive
    information via the Session Extension changeset concat/changegroup merge path(CVE-2026-50813)

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

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