Ubuntu 22.04 LTS / 24.04 LTS : Python-Multipart vulnerabilities (USN-8027-1)

high Nessus Plugin ID 298807

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-8027-1 advisory.

 It was discovered that Python-Multipart incorrectly handled certain

 regular expressions. An attacker could possibly use this issue to cause Python-Multipart to consume excessive resources, leading to a regular

 expression denial of service. This issue only affected Ubuntu 22.04 LTS. (CVE-2024-24762)

 It was discovered that Python-Multipart did not properly sanitize line breaks during user input. An attacker could use this issue to send

 arbitrary input, thus preventing other requests from being processed,

 resulting in a denial of service. This issue was only fixed in

 Ubuntu 24.04 LTS. (CVE-2024-53981)

 It was discovered that Python-Multipart was vulnerable to path traversal attacks. An attacker could possibly craft and upload files outside the

 target directory, resulting in remote code execution. (CVE-2026-24486)

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

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

Solution

Update the affected python3-multipart package.
