"PulseAudio 0.9.5 allows remote attackers to cause a denial of service (daemon
crash) via (1) a PA_PSTREAM_DESCRIPTOR_LENGTH value of FRAME_SIZE_MAX_ALLOW sent
on TCP port 9875, which triggers a p->export assertion failure in do_read; (2) a
PA_PSTREAM_DESCRIPTOR_LENGTH value of 0 sent on TCP port 9875, which triggers a
length assertion failure in pa_memblock_new; or (3) an empty packet on UDP port
9875, which triggers a t assertion failure in pa_sdp_parse; and allows remote
authenticated users to cause a denial of service (daemon crash) via a crafted
packet on TCP port 9875 that (4) triggers a maxlength assertion failure in
pa_memblockq_new, (5) triggers a size assertion failure in pa_xmalloc, or (6)
plays a certain sound file."

FC5, FC6, devel have 0.9.5 at the moment.

PulseAudio 0.9.6 fixes these issues.

Comment 2 Lennart Poettering 2007-09-07 10:23:31 UTC

This has been fixed for quite a while in Rawhide. Since these all are issues
that only trigger an assert() they are quite a low priority. Also, to trigger
them some non-standard modules need to be loaded into the sound server. Thus, I
so no need to provide updates for FC5/FC6.
