A use-after-free vulnerability was found in usbredir in versions prior to 0.11.0 in the usbredirparser_serialize() in usbredirparser/usbredirparser.c. This issue occurs when serializing large amounts of buffered write data in the case of a slow or blocked destination.

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

  - A use-after-free vulnerability was found in usbredir in versions prior to 0.11.0 in the     usbredirparser_serialize() in usbredirparser/usbredirparser.c. This issue occurs when serializing large     amounts of buffered write data in the case of a slow or blocked destination. (CVE-2021-3700)

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

According to the versions of the usbredir package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - A use-after-free vulnerability was found in usbredir in versions prior to 0.11.0 in the     usbredirparser_serialize() in usbredirparser/usbredirparser.c. This issue occurs when serializing large     amounts of buffered write data in the case of a slow or blocked destination. (CVE-2021-3700)

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5784-1 advisory.

    It was discovered that usbredir incorrectly handled memory when serializing large amounts of data in the     case of a slow or blocked destination. An attacker could possibly use this issue to cause applications     using usbredir to crash, resulting in a denial of service, or possibly execute arbitrary code.

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

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

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2958 advisory.

    A use-after-free vulnerability was found in Usbredirparser, a parser for the usbredir protocol, which     could result in denial of service or potentially arbitrary code execution. For Debian 9 stretch, this     problem has been fixed in version 0.7.1-1+deb9u1. We recommend that you upgrade your usbredir packages.
