Audacity is a free cross-platform audio editor.
Houssamix discovered a boundary error in the String_parse::get_nonspace_quoted() function in lib-src/allegro/strparse.cpp.
A remote attacker could entice a user into importing a specially crafted *.gro file, resulting in the execution of arbitrary code or a Denial of Service.
There is no known workaround at this time.
All Audacity users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/audacity-1.3.6"
