The remote MiracleLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2021-2804:10 advisory.

    * python-pygments: Infinite loop in SML lexer may lead to DoS (CVE-2021-20270)
      * python-pygments: ReDoS in multiple lexers (CVE-2021-27291)

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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

The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:4150 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.

According to the versions of the python-pygments packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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.(CVE-2021-27291)

It was found that pygments, a generic syntax highlighter, is vulnerable to a CPU exhaustion attack via a crafted SML file.

For Debian 9 stretch, this problem has been fixed in version 2.2.0+dfsg-1+deb9u1.

We recommend that you upgrade your pygments packages.
