Integer overflow in the writepng function in cairo 1.14.6 allows remote attackers to cause a denial of service (invalid pointer dereference) via a large svg file.

cairo 1.16.0, in cairoftapplyvariations() in cairo-ft-font.c, would free memory using a free function incompatible with WebKit's fastMalloc, leading to an application crash with a "free(): invalid pointer" error.

The cairoimagesurfacegetdata function in Cairo 1.10.2, as used in GTK+ and Wireshark, allows context-dependent attackers to cause a denial of service (NULL pointer dereference) via a large string.

Cairo version 1.15.4 is vulnerable to a NULL pointer dereference related to the FTLoadGlyph and FTRenderGlyph resulting in an application crash.
