ArchLinux: 201902-19: cairo: arbitrary code execution
Summary
A memory-corruption issue has been found in cairo versions <= 1.16.0, in the cairo_ft_apply_variations() function in cairo-ft-font.c. This function frees memory using the wrong free function, leading to memory corruption. As cairo is used, among others, by WebKitGTK+, this could be triggered by a crafted web content in some cases.
Resolution
Upgrade to 1.16.0-2.
# pacman -Syu "cairo>=1.16.0-2"
The problem has been fixed upstream but no release is available yet.
