## Description

Heap buffer overflow in PostgreSQL pg\_trgm allows a database user to
achieve unknown impacts via a crafted input string. The attacker has
limited control over the byte patterns to be written, but we have not ruled
out the viability of attacks that lead to privilege escalation. PostgreSQL
18.1 and 18.0 are affected.
