NVD Description

Note: Versions mentioned in the description apply only to the upstream libsass package and not the libsass package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

In LibSass prior to 3.5.5, the function handle_error in sass_context.cpp allows attackers to cause a denial-of-service resulting from a heap-based buffer over-read via a crafted sass file.
