INN is a news server which can interface with Usenet.
INN’s I/O buffering is not correctly restricted.
A remote attacker could inject commands into encrypted NNTP sessions.
There is no known workaround at this time.
All INN users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-nntp/inn-2.5.3"
