Exploited in the last 30 days

uTox through 0.18.1 contains a path traversal vulnerability that allows Tox friends to write arbitrary files by sending absolute or ../ file names to victims with auto-accept enabled. Attackers can overwrite shell startup files or plant crafted .ftinfo resume records that ft_find_resumeable() loads, abusing FILE pointers to write /proc/self/mem and execute code.
