FreeBSD : strongswan -- buffer overflow (bbda3d16-968e-11ee-b780-b42e991fc52e)

critical Nessus Plugin ID 186708



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


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 bbda3d16-968e-11ee-b780-b42e991fc52e advisory.

- strongSwan before 5.9.12 has a buffer overflow and possible unauthenticated remote code execution via a DH public value that exceeds the internal buffer in charon-tkm's DH proxy. The earliest affected version is 5.3.0. An attack can occur via a crafted IKE_SA_INIT message. (CVE-2023-41913)

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


Update the affected packages.
