Marked is a markdown parser and compiler. Prior to version 4.0.10, the regular expression `block.def` may cause catastrophic backtracking against some strings and lead to a regular expression denial of service (ReDoS). Anyone who runs untrusted markdown through a vulnerable version of marked and does not use a worker with a time limit may be affected. This issue is patched in version 4.0.10. As a workaround, avoid running untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit to prevent draining resources.

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

Anyone who runs untrusted markdown through a vulnerable version of marked and does not use a     worker with a time limit may be affected. This issue is patched in version 4.0.10. As a workaround, avoid     running untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit     to prevent draining resources. (CVE-2022-21680)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - Marked is a markdown parser and compiler. Prior to version 4.0.10, the regular expression `block.def` may
    cause catastrophic backtracking against some strings and lead to a regular expression denial of service
    (ReDoS). Anyone who runs untrusted markdown through a vulnerable version of marked and does not use a
    worker with a time limit may be affected. This issue is patched in version 4.0.10. As a workaround, avoid
    running untrusted markdown through marked or run marked on a worker thread and set a reasonable time limit
    to prevent draining resources. (CVE-2022-21680)

The version of IBM Cognos Analytics installed on the remote host is 11.1.x prior to 11.1.7 Fix Pack 7 or 11.2.x prior to 11.2.4 FP1. It is, therefore, affected by multiple vulnerabilities, including the following:

  - GNOME libxml2 could allow a remote attacker to execute arbitrary code on the system, caused by a use-after-free     flaw in the xmlXIncludeDoProcess() function in xinclude.c. By sending a specially-crafted file, an attacker could     exploit this vulnerability to execute arbitrary code on the system. (CVE-2021-3518)

  - Node.js could allow a local attacker to gain elevated privileges on the system, caused by the DLL search order     hijacking of providers.dll. By placing a specially crafted file, an attacker could exploit this vulnerability     to escalate privileges. (CVE-2022-32223)

  - Node.js marked module is vulnerable to a denial of service, caused by a regular expression denial of service     (ReDoS) flaw in inline.reflinkSearch. By sending a specially-crafted regex input, a remote attacker could exploit     this vulnerability to cause a denial of service condition. (CVE-2022-21681)

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

The remote Fedora 36 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2022-784d729f30 advisory.
