FreeBSD : Matrix clients -- several vulnerabilities (0dcf68fa-5c31-11ec-875e-901b0e9408dc)

high Nessus Plugin ID 156036

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 0dcf68fa-5c31-11ec-875e-901b0e9408dc advisory.

 - Matrix developers report: Today we are releasing security updates to libolm, matrix-js-sdk, and several clients including Element Web / Desktop. Users are encouraged to upgrade as soon as possible. These releases mitigate a buffer overflow in olm_session_describe, a libolm debugging function used by matrix-js-sdk in its end-to-end encryption (E2EE) implementation. If you rely on matrix-js-sdk for E2EE, you are affected. (0dcf68fa-5c31-11ec-875e-901b0e9408dc)

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.
