bugs. We recommend this upgrade for all CVS clients and servers!"

There is no known workaround at this time.
All Gentoo Linux machines with cvs installed should be updated to use
dev-util/cvs-1.11.10 or higher:
Code Listing 3.1: Resolution
# emerge sync
# emerge -pv '>=dev-util/cvs-1.11.10'
# emerge '>=dev-util/cvs-1.11.10'
# emerge clean
