NVD Description

Note: Versions mentioned in the description apply only to the upstream libgrss package and not the libgrss package as distributed by Alpine. See How to fix? for Alpine:3.15 relevant fixed versions and status.

libgrss through 0.7.0 fails to perform TLS certificate verification when downloading feeds, allowing remote attackers to manipulate the contents of feeds without detection. This occurs because of the default behavior of SoupSessionSync.
