From 1c72446ef69cf6c50cf9b2dae69b2b24a7576103 Mon Sep 17 00:00:00 2001 From: unknown Date: Mon, 26 Nov 2007 09:13:23 +0100 Subject: [PATCH] Bug#31752: check strmake() bounds strmake() called with wrong parameters: 5.0-specific fixes. client/mysql.cc: In debug-mode, strmake() fills unused part of buffer with a test-pattern. This overwrites our previous extra '\0' (from previous bzero()). sql/sp.cc: off-by-one buffer-size. --- client/mysql.cc | 5 ++++- sql/sp.cc | 2 +- 2 files changed, 5 insertions(+), 2 deletions(-) diff --git a/client/mysql.cc b/client/mysql.cc index 8e1b6c2a9b4..ff2c1d228cd 100644 --- a/client/mysql.cc +++ b/client/mysql.cc @@ -2987,7 +2987,10 @@ com_connect(String *buffer, char *line) Two null bytes are needed in the end of buff to allow get_arg to find end of string the second time it's called. */ - strmake(buff, line, sizeof(buff)-2); + tmp= strmake(buff, line, sizeof(buff)-2); +#ifdef EXTRA_DEBUG + tmp[1]= 0; +#endif tmp= get_arg(buff, 0); if (tmp && *tmp) { diff --git a/sql/sp.cc b/sql/sp.cc index 75d6fa4618f..bae5933aec1 100644 --- a/sql/sp.cc +++ b/sql/sp.cc @@ -1902,7 +1902,7 @@ sp_use_new_db(THD *thd, LEX_STRING new_db, LEX_STRING *old_db, if (thd->db) { - old_db->length= (strmake(old_db->str, thd->db, old_db->length) - + old_db->length= (strmake(old_db->str, thd->db, old_db->length - 1) - old_db->str); } else
