OpenSLP is an open-source implementation of Service Location Protocol (SLP).
Multiple buffer overflows have been found in OpenSLP, when handling malformed SLP packets.
By sending specially crafted SLP packets, a remote attacker could potentially execute arbitrary code with the rights of the OpenSLP daemon.
There is no known workaround at this time.
All OpenSLP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-libs/openslp-1.2.1"
