Description Pedro Sampaio 2018-06-07 16:47:13 UTC 
An issue was discovered in Libsass through 3.5.4. An out-of-bounds read of a memory region was found in the function Sass::handle_error which could be leveraged by an attacker to disclose information or manipulated to read from unmapped memory causing a denial of service.
