These values are multiplied and assigned to an int when -reading the image, what can cause integer overflows. We have to avoid -that, and also make sure that either chunk count is actually greater -than zero. If illegal chunk counts are detected, we bail out from -reading the image. - -Upstream-Status: Backport -CVE: CVE-2016-10168 - -Signed-off-by: Catalin Enache <catalin.enache@windriver.com> ---- - src/gd_gd2.c | 4 ++++ - 1 file changed, 4 insertions(+) - -diff --git a/src/gd_gd2.c b/src/gd_gd2.c -index bae65ea..9006bd2 100644 ---- a/src/gd_gd2.c -+++ b/src/gd_gd2.c -@@ -151,6 +151,10 @@ _gd2GetHeader (gdIOCtxPtr in, int *sx, int *sy, - GD2_DBG (printf ("%d Chunks vertically\n", *ncy)); - - if (gd2_compressed (*fmt)) { -+ if (*ncx <= 0 || *ncy <= 0 || *ncx > INT_MAX / *ncy) { -+ GD2_DBG(printf ("Illegal chunk counts: %d * %d\n", *ncx, *ncy)); -+ goto fail1; -+ } - nc = (*ncx) * (*ncy); - - GD2_DBG (printf ("Reading %d chunk index entries\n", nc)); --- -2.10.2 - |
