File CVE-2015-8863.patch of Package jq
From 8eb1367ca44e772963e704a700ef72ae2e12babd Mon Sep 17 00:00:00 2001 From: Nicolas Williams <nico@cryptonector.com> Date: Sat, 24 Oct 2015 17:24:57 -0500 Subject: [PATCH] Heap buffer overflow in tokenadd() (fix #105) This was an off-by one: the NUL terminator byte was not allocated on resize. This was triggered by JSON-encoded numbers longer than 256 bytes. --- src/jv_parse.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) Index: b/jv_parse.c =================================================================== --- a/jv_parse.c +++ b/jv_parse.c @@ -383,7 +383,7 @@ static pfunc stream_token(struct jv_pars static void tokenadd(struct jv_parser* p, char c) { assert(p->tokenpos <= p->tokenlen); - if (p->tokenpos == p->tokenlen) { + if (p->tokenpos >= (p->tokenlen - 1)) { p->tokenlen = p->tokenlen*2 + 256; p->tokenbuf = jv_mem_realloc(p->tokenbuf, p->tokenlen); } @@ -485,7 +485,7 @@ static pfunc check_literal(struct jv_par TRY(value(p, v)); } else { // FIXME: better parser - p->tokenbuf[p->tokenpos] = 0; // FIXME: invalid + p->tokenbuf[p->tokenpos] = 0; char* end = 0; double d = jvp_strtod(&p->dtoa, p->tokenbuf, &end); if (end == 0 || *end != 0)
