From c26872ed59cba3af2f407b5eefc92fcec92aa52b Mon Sep 17 00:00:00 2001 From: Ben Wagner Date: Thu, 26 May 2022 20:27:53 -0400 Subject: [PATCH] [svg] Clear correct flags for doc ownership This issue was discovered with an SVG based font with some documents compressed and other uncompressed. After loading the first compressed document the ownership flag on the glyph slot was set to true but never set to false. As a result after loading a compressed document a glyph from an uncompressed document would load fine, but when this glyph slot was cleared it would try to free its document resulting in a wild free. * src/base/ftobjs.c (ft_glyphslot_clear): clear correct flags Fixes: #1162 --- src/base/ftobjs.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/base/ftobjs.c b/src/base/ftobjs.c index eeda69c3e..f66273f3d 100644 --- a/src/base/ftobjs.c +++ b/src/base/ftobjs.c @@ -605,7 +605,7 @@ FT_FREE( doc->svg_document ); - slot->internal->load_flags &= ~FT_GLYPH_OWN_GZIP_SVG; + slot->internal->flags &= ~FT_GLYPH_OWN_GZIP_SVG; } } #endif
