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

    SQLite before 3.53.2 contains a heap-based buffer overflow vulnerability in the FTS5 full-text search
    extension that allows attackers to cause a crash or execute arbitrary code by supplying a crafted database
    with malicious continuation page metadata specifying a szLeaf value smaller than 4. Attackers can trigger
    an integer underflow in fts5ChunkIterate() causing an inflated remaining byte count during FTS5 MATCH
    query processing, leading to a heap buffer overflow of attacker-controlled data in applications compiled
    with SQLITE_ENABLE_FTS5.(CVE-2026-11824)

    SQLite before 3.53.2 contains memory corruption vulnerabilities in the FTS5 full-text search extension
    that allow attackers to cause process crashes, memory exhaustion, or arbitrary code execution by supplying
    a crafted database with malformed FTS5 page data. Attackers can trigger an out-of-bounds read in
    fts5LeafSeek() via an attacker-controlled loop bound and a heap buffer overflow write in
    fts5ChunkIterate() through a crafted continuation page causing an integer underflow, exploitable when an
    FTS5 MATCH query is executed against the malicious database.(CVE-2026-11822)

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.");
