Linux Distros Unpatched Vulnerability : CVE-2018-19826

medium Nessus Plugin ID 222329

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- In inspect.cpp in LibSass 3.5.5, a high memory footprint caused by an endless loop (containing a Sass::Inspect::operator()(Sass::String_Quoted*) stack frame) may cause a Denial of Service via crafted sass input files with stray '&' or '/' characters. NOTE: Upstream comments indicate this issue is closed as won't fix and works as intended by design (CVE-2018-19826)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
