A flaw was found in cairo's image-compositor.c in all versions prior to 1.17.4. This flaw allows an attacker who can provide a crafted input file to cairo's image-compositor (for example, by convincing a user to open a file in an application using cairo, or if an application uses cairo on untrusted input) to cause a stack buffer overflow -> out-of-bounds WRITE. The highest impact from this vulnerability is to confidentiality, integrity, as well as system availability.

An issue was discovered in cairo 1.16.0. There is an assertion problem in the function cairoarcindirection in the file cairo-arc.c.

An issue was discovered in cairo 1.16.0. There is an infinite loop in the function arcerrornormalized in the file cairo-arc.c, related to arcmaxanglefortolerancenormalized.

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.

cairo through 1.15.14 has an out-of-bounds stack-memory write during processing of a crafted document by WebKitGTK+ because of the interaction between cairo-rectangular-scan-converter.c (the generate and renderrows functions) and cairo-image-compositor.c (the cairoimagespansandzero function).

cairo-truetype-subset.c in cairo 1.15.6 and earlier allows remote attackers to cause a denial of service (out-of-bounds read) because of mishandling of an unexpected malloc(0) call.

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

A vulnerability was found in cairo. A maliciously crafted file can cause out of bounds read in fillxrgb32lerpopaquespans function in cairo, thus crashing the software.

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.

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.
