-Subject: [PATCH] Detect a possible overflow directly in the TLV parser.
-
-* src/ber-help.c (_ksba_ber_read_tl): Check for overflow of a commonly
-used sum.
---
-
-It is quite common to have checks like
-
-    if (ti.nhdr + ti.length >= DIM(tmpbuf))
-       return gpg_error (GPG_ERR_TOO_LARGE);
-
-This patch detects possible integer overflows immmediately when
-creating the TI object.
