Fix CVE(s): CVE-2026-19385
Type: advisorySources: OSV
* SECURITY UPDATE: Out-of-bounds read in pg_dump on long protrftypes. dumpFunc() parsed pg_proc.protrftypes into a fixed FUNC_MAX_ARGS array that is not zero-terminated when the server reports exactly FUNC_MAX_ARGS entries, so the TRANSFORM loop read past the buffer; a function with more entries made pg_dump abort. Any role that can create functions in a language with a transform could thus break or corrupt dumps. - debian/patches/CVE-2026-19385.patch: make parseOidArray() allocate the array itself (exact count, or input-sized and zero-terminated), add parseIntArray() for pg_index.indkey, and use them in getAggregates(), getFuncs(), getIndexes() and dumpFunc(); add a function with a transform to the object_address regression test (upstream 57aa21f691; older-server branches of 9.5 pg_dump kept). - CVE-2026-19385
