Oracle Linux 8 : resource-agents (ELSA-2021-9553)

high Nessus Plugin ID 155615

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2021-9553 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.
(CVE-2021-27291)

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

Solution

Update the affected resource-agents package.
