From: Derek Wang <derek.w...@sun.com> This fixes a crash reported when selecting "View Page Source" in Mozilla on Solaris 10, due to invalid parameters being given to XPutImage.
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6261221 Signed-off-by: Alan Coopersmith <alan.coopersm...@oracle.com> --- I can't claim to understand this patch, but it's been shipping in Solaris libXft for 5 years, so it's a bit overdue to attempt pushing it upstream. (Unfortunately, that's also almost how long it's been since the original author left Sun.) Given the timeframe & hardware on which it was reported, I suspect it affects the libXft fallback path to use libX11 when the Render extension is not available, but have not confirmed that. src/xftcore.c | 10 ++++++++++ 1 files changed, 10 insertions(+), 0 deletions(-) diff --git a/src/xftcore.c b/src/xftcore.c index 3f87109..a0103cf 100644 --- a/src/xftcore.c +++ b/src/xftcore.c @@ -1253,7 +1253,17 @@ XftGlyphFontSpecCore (XftDraw *draw, if (i) { if (g_x1 < x1) + { + if (g_x1 < 0) + { + /* do nothing if the given glyphs are out of range */ + short t = glyphs[i-1].font->max_advance_width + + glyphs[i-1].x; + if (t < 0 && glyphs[i-1].x > 0) + goto bail1; + } x1 = g_x1; + } if (g_y1 < y1) y1 = g_y1; if (g_x2 > x2) -- 1.7.3.2 _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
