Security researcher Francisco Alonso of the NowSecure Research Team used the Address Sanitizer tool to discover an out-of-bounds read issue during 2D canvas rendering. This was due to an issue in the cairo graphics library when surfaces are created with 32-bit color depth but displayed on a 16-bit color depth system, which is unsupported. This allows an attacker to read an amount of random memory following the heap for the 16-bit surface leading to information disclosure.
This issue is specific to Linux in certain configurations and does not affect Windows or OS X systems.
