librsvg: CVE-2011-3146 Store node type separately in RsvgNode commit 34c95743ca692ea0e44778e41a7c0a129363de84 upstream The node name (formerly RsvgNode:type) cannot be used to infer the sub-type of RsvgNode that we're dealing with, since for unknown elements we put type = node-name. This lead to a (potentially exploitable) crash e.g. when the element name started with "fe" which tricked the old code into considering it as a RsvgFilterPrimitive. http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2011-3146 https://bugzilla.gnome.org/show_bug.cgi?id=658014 --- rsvg-base.c | 68 ++++++++++++++++++++++++++------------------ rsvg-cairo-draw.c | 2 +- rsvg-filter.c | 79 +++++++++++++++++++++++++++------------------------ rsvg-filter.h | 2 +- rsvg-image.c | 2 +- rsvg-marker.c | 4 +- rsvg-mask.c | 8 ++-- rsvg-paint-server.c | 25 ++++++++-------- rsvg-private.h | 60 ++++++++++++++++++++++++++++++++++++++- rsvg-shapes.c | 25 ++++++++-------- rsvg-shapes.h | 2 +- rsvg-structure.c | 25 ++++++++-------- rsvg-structure.h | 5 ++- rsvg-text.c | 22 ++++++++------ 14 files changed, 204 insertions(+), 125 deletions(-) diff --git a/rsvg-base.c b/rsvg-base.c index 1f5c48c..b1a2d8b 100644 --- a/rsvg-base.c +++ b/rsvg-base.c @@ -147,7 +147,6 @@ rsvg_start_style (RsvgHandle * ctx, RsvgPropertyBag * atts) static void rsvg_standard_element_start (RsvgHandle * ctx, const char *name, RsvgPropertyBag * atts) { - /*replace this stuff with a hash for fast reading! */ RsvgNode *newnode = NULL;
