The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the cdc685b5-1724-49a1-ad57-2eaab68e9cc0 advisory.

  - An infinite loop in SMLLexer in Pygments versions 1.5 to 2.7.3 may lead to denial of service when     performing syntax highlighting of a Standard ML (SML) source file, as demonstrated by input that only     contains the exception keyword. (CVE-2021-20270)

  - In pygments 1.1+, fixed in 2.7.4, the lexers used to parse programming languages rely heavily on regular     expressions. Some of the regular expressions have exponential or cubic worst-case complexity and are     vulnerable to ReDoS. By crafting malicious input, an attacker can cause a denial of service.
