What is CVE-2018-11319?
CVE-2018-11319 is a high-severity path traversal vulnerability in Debian Debian Linux, published on 20 May 2018. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Syntastic (aka vim-syntastic) through 3.9.0 does not properly handle searches for configuration files (it searches the current directory up to potentially the root). This improper handling might be exploited for arbitrary code execution via a malicious gcc plugin, if an attacker has write access to a directory that is a parent of the base directory of the project being checked. NOTE: exploitation is more difficult after 3.8.0 because filename prediction may be needed.
