FreeBSD : fetchmail -- two vulnerabilities in NTLM authentication (83f9e943-e664-11e1-a66d-080027ef73ec)

medium Nessus Plugin ID 61539
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Matthias Andree reports :

With NTLM support enabled, fetchmail might mistake a server-side error message during NTLM protocol exchange for protocol data, leading to a SIGSEGV.

Also, with a carefully crafted NTLM challenge, a malicious server might cause fetchmail to read from a bad memory location, betraying confidential data. It is deemed hard, although not impossible, to steal other accounts' data.

Solution

Update the affected package.
