Description OSIDB Bzimport 2026-08-13 13:30:39 UTC 
Buffer over-read in PostgreSQL ascii() SQL function allows a user to disclose up to 3 bytes after the end of a specific allocation, via a crafted text value.  This is the same class of defect that CVE-2026-2006 fixed, though this instance has less impact.  Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.
