Stack overflow vulnerability in ast_selectors.cpp in function Sass::CompoundSelector::has_real_parent_ref in libsass:3.6.5-8-g210218, which can be exploited by attackers to causea denial of service (DoS). Also affects the command line driver for libsass, sassc 3.6.2.

The version of libsass installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-43357 advisory.

  - Stack overflow vulnerability in ast_selectors.cpp in function Sass::CompoundSelector::has_real_parent_ref     in libsass:3.6.5-8-g210218, which can be exploited by attackers to causea denial of service (DoS). Also     affects the command line driver for libsass, sassc 3.6.2. (CVE-2022-43357)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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