CVE Published:

Summary

The GNOME Evolution RSS application, specifically in versions up to 0.3.96, contains a flaw in its network-soup.c component, where the SoupSessionSync objects it generates do not activate TLS certificate verification. This oversight renders users susceptible to man-in-the-middle (MITM) attacks, where an attacker could intercept and potentially manipulate the data transmitted over the network. This vulnerability is similar to previous issues noted in related components, emphasizing the criticality of proper certificate validation in maintaining secure communications.
