I sent this patch upstream. Since it only touches nss_hesiod, which is completely broken otherwise, it should be very low risk. https://sourceware.org/ml/libc-alpha/2016-04/msg00563.html 2016-04-22 Anders Kaseorg <ande...@mit.edu> [BZ #19573] * hesiod/hesiod.c (hesiod_end): Only call res_nclose(ctx->res) if ctx->free_res is nonnull, to prevent a crash on res_nclose(&res) introduced by commit 2212c1420c92a33b0e0bd9a34938c9814a56c0f7 (Simplify handling of nameserver configuration in resolver). diff --git a/hesiod/hesiod.c b/hesiod/hesiod.c index 657dabe..a540382 100644 --- a/hesiod/hesiod.c +++ b/hesiod/hesiod.c @@ -152,12 +152,12 @@ hesiod_end(void *context) { struct hesiod_p *ctx = (struct hesiod_p *) context; int save_errno = errno; - if (ctx->res) + if (ctx->res && ctx->free_res) { res_nclose(ctx->res); + (*ctx->free_res)(ctx->res); + } free(ctx->RHS); free(ctx->LHS); - if (ctx->res && ctx->free_res) - (*ctx->free_res)(ctx->res); free(ctx); __set_errno(save_errno); } Anders
