Sqlite

Heap-based buffer overflow in SQLite's FTS5 full-text search extension (versions before 3.53.2) allows attackers to crash the process or execute arbitrary code by supplying a malicious database file that triggers an integer underflow in fts5ChunkIterate() during MATCH query processing. The flaw affects any application compiled with SQLITE_ENABLE_FTS5 that opens an attacker-supplied database and runs an FTS5 query against it; no public exploit identified at time of analysis, though VulnCheck has published an advisory.

Memory corruption in SQLite versions before 3.53.2 enables attackers to crash processes, exhaust memory, or potentially execute arbitrary code by supplying a crafted database that triggers flaws in the FTS5 full-text search extension when a MATCH query runs. The CVSS 4.0 vector indicates local attack vector with passive user interaction required, and no public exploit identified at time of analysis. Reported by VulnCheck with patches already merged upstream.

SQLite's zipfile extension contains a bug in the zipfileInflate function that leaks heap memory contents when processing specially crafted ZIP files. This affects SQLite version 3.51.1 and earlier installations that use the zipfile extension. An attacker can exploit this by providing a malicious ZIP file to read sensitive data from the application's memory, potentially exposing passwords, encryption keys, or other confidential information.

Memory corruption in SQLite versions before 3.50.2 allows network-based attackers with low privileges to manipulate aggregate queries causing integrity impacts.

No confirmed active exploitation (not in CISA KEV), though multiple security advisories from Siemens and OSS-security mailing lists indicate broad downstream impact across industrial control systems and embedded products using SQLite.
