SQLite < 3.53.2 Multiple Heap Buffer Overflows

high Nessus Plugin ID 321188

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of SQLite installed on the remote host is prior to 3.53.2. It is, therefore, affected by multiple vulnerabilities:

 - A heap-based buffer overflow vulnerability in the FTS5 full-text search extension 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. An integer underflow in fts5ChunkIterate() causes an inflated remaining byte count during FTS5 MATCH query processing, leading to a heap buffer overflow of attacker-controlled data. (CVE-2026-11824)

 - Memory corruption vulnerabilities in the FTS5 full-text search extension allow attackers to cause process crashes, memory exhaustion, or arbitrary code execution by supplying a crafted database with malformed FTS5 page data. 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 are exploitable when an FTS5 MATCH query is executed against the malicious database.
 (CVE-2026-11822)

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

Solution

Upgrade to SQLite 3.53.2 or later.
