Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow via the fts5ChunkIterate() function in the FTS5 full-text search extension. An attacker can cause a crash or execute arbitrary code by supplying a crafted database with malicious continuation page metadata that triggers an integer underflow, resulting in a heap buffer overflow of attacker-controlled data during FTS5 MATCH query processing.
Note:
This is only exploitable if the application is compiled with SQLITE_ENABLE_FTS5.
