And malloc(0) is not returning -NULL as some people could expect: - - https://stackoverflow.com/questions/1073157/zero-size-malloc - -malloc(0) returns the smallest chunk possible. So the line 1290 -with the return is not execute. And the execution continues with -an invalid map. - -Since the size is 0 the variable map is not initialized correctly -at load_trutype_table. So, later when the variable map is accessed -previous values from a freed chunk are used. This could allows an -attacker to control the variable map. - -This patch have not merge in upstream now. - -Upstream-Status: Backport [https://bugs.freedesktop.org/show_bug.cgi?id=101547] -CVE: CVE-2017-9814 -Signed-off-by: Dengke Du <dengke.du@windriver.com> ---- - src/cairo-truetype-subset.c | 2 +- - 1 file changed, 1 insertion(+), 1 deletion(-) - -diff --git a/src/cairo-truetype-subset.c b/src/cairo-truetype-subset.c -index e3449a0..f77d11c 100644 ---- a/src/cairo-truetype-subset.c -+++ b/src/cairo-truetype-subset.c -@@ -1285,7 +1285,7 @@ _cairo_truetype_reverse_cmap (cairo_scaled_font_t *scaled_font, - return CAIRO_INT_STATUS_UNSUPPORTED; - - size = be16_to_cpu (map->length); -- map = malloc (size); -+ map = _cairo_malloc (size); - if (unlikely (map == NULL)) - return _cairo_error (CAIRO_STATUS_NO_MEMORY); - --- -2.8.1 - diff --git a/poky/meta/recipes-graphics/cairo/cairo/CVE-2018-19876.patch b/poky/meta/recipes-graphics/cairo/cairo/CVE-2018-19876.patch new file mode 100644 index 000000000..4252a5663 --- /dev/null +++ b/poky/meta/recipes-graphics/cairo/cairo/CVE-2018-19876.patch @@ -0,0 +1,34 @@ +CVE: CVE-2018-19876 +Upstream-Status: Backport +Signed-off-by: Ross Burton <ross.burton@intel.com> + +From 90e85c2493fdfa3551f202ff10282463f1e36645 Mon Sep 17 00:00:00 2001 +From: Carlos Garcia Campos <cgarcia@igalia.com> +Date: Mon, 19 Nov 2018 12:33:07 +0100 +Subject: [PATCH] ft: Use FT_Done_MM_Var instead of free when available in + cairo_ft_apply_variations + +Fixes a crash when using freetype >= 2.9 +--- + src/cairo-ft-font.c | 4 ++++ + 1 file changed, 4 insertions(+) + +diff --git a/src/cairo-ft-font.c b/src/cairo-ft-font.c +index 325dd61b4..981973f78 100644 +--- a/src/cairo-ft-font.c ++++ b/src/cairo-ft-font.c +@@ -2393,7 +2393,11 @@ skip: + done: + free (coords); + free (current_coords); ++#if HAVE_FT_DONE_MM_VAR ++ FT_Done_MM_Var (face->glyph->library, ft_mm_var); ++#else + free (ft_mm_var); ++#endif + } + } + +-- +2.11.0 + diff --git a/poky/meta/recipes-graphics/cairo/cairo/CVE-2019-6461.patch b/poky/meta/recipes-graphics/cairo/cairo/CVE-2019-6461.patch new file mode 100644 index 000000000..5232cf70c --- /dev/null +++ b/poky/meta/recipes-graphics/cairo/cairo/CVE-2019-6461.patch @@ -0,0 +1,19 @@ +There is a potential infinite-loop in function _arc_error_normalized(). + +CVE: CVE-2019-6461 +Upstream-Status: Pending +Signed-off-by: Ross Burton <ross.burton@intel.com> + +diff --git a/src/cairo-arc.c b/src/cairo-arc.c +index 390397bae..f9249dbeb 100644 +--- a/src/cairo-arc.c ++++ b/src/cairo-arc.c +@@ -99,7 +99,7 @@ _arc_max_angle_for_tolerance_normalized (double tolerance) + do { + angle = M_PI / i++; + error = _arc_error_normalized (angle); +- } while (error > tolerance); ++ } while (error > tolerance && error > __DBL_EPSILON__); + + return angle; + } diff --git a/poky/meta/recipes-graphics/cairo/cairo/CVE-2019-6462.patch b/poky/meta/recipes-graphics/cairo/cairo/CVE-2019-6462.patch new file mode 100644 index 000000000..4e4598c5b --- /dev/null +++ b/poky/meta/recipes-graphics/cairo/cairo/CVE-2019-6462.patch @@ -0,0 +1,20 @@ +There is an assertion in function _cairo_arc_in_direction(). + +CVE: CVE-2019-6462 +Upstream-Status: Pending +Signed-off-by: Ross Burton <ross.burton@intel.com> + +diff --git a/src/cairo-arc.c b/src/cairo-arc.c +index 390397bae..1bde774a4 100644 +--- a/src/cairo-arc.c ++++ b/src/cairo-arc.c +@@ -186,7 +186,8 @@ _cairo_arc_in_direction (cairo_t *cr, + if (cairo_status (cr)) + return; + +- assert (angle_max >= angle_min); ++ if (angle_max < angle_min) ++ return; + + if (angle_max - angle_min > 2 * M_PI * MAX_FULL_CIRCLES) { + angle_max = fmod (angle_max - angle_min, 2 * M_PI); |
