CVE-2025-24792

Application crash via unchecked negative column count

Published Jan 29, 2025 · Updated Feb 12, 2025

Denial of service in Snowflake PHP PDO Driver 0.2.0 through 3.0.3 allows local users to crash applications via unsupported stage queries. The driver treats a -1 query error code as a returned-column count, casts it to size_t, and uses the resulting value in a memory allocation. Exploitation requires low privileges and user interaction, and the PHP runtime error terminates the application without affecting data confidentiality or integrity.
