FreeBSD : security/openvpn-auth-ldap -- Fix buffer overflow in challenge/response (e915b60e-ea25-11ef-a1c0-0050569f0b83)

medium Nessus Plugin ID 216253

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 e915b60e-ea25-11ef-a1c0-0050569f0b83 advisory.

 Graham Northup reports:
 A buffer overflow in extract_openvpn_cr allows attackers with a valid LDAP username and who can control the challenge/response password field to pass a string with more than 14 colons into this field and cause a buffer overflow.

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

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.
