(not sandboxed) firefox AVCs (execstack)

[Christoph A.]

Hi,

by coincidence I saw the following AVCs in my audit log when starting
firefox (firefox runs fine).

type=1400 audit(1307056986.733:2965): avc:  denied  { execstack } for
pid=13470 comm="plugin-config"
scontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023

tclass=process

Should I classify these AVCs as suspicious?
