FreeBSD : amavisd-new -- multipart boundary confusion (0a48e552-e470-11ee-99b3-589cfc0f81b0)

high Nessus Plugin ID 192186

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 0a48e552-e470-11ee-99b3-589cfc0f81b0 advisory.

 - The Amavis project reports: Emails which consist of multiple parts (`Content-Type: multipart/*`) incorporate boundary information stating at which point one part ends and the next part begins.
 A boundary is announced by an Content-Type header's `boundary` parameter. To our current knowledge, RFC2046 and RFC2045 do not explicitly specify how a parser should handle multiple boundary parameters that contain conflicting values. As a result, there is no canonical choice which of the values should or should not be used for mime part decomposition. (CVE-2024-28054)

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 packages.
