This vulnerability has a CVSS 2.0 base score of 7.8, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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.
Remediation
Check the references section for vendor advisories and patches from pulseaudio. Update pulseaudio to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
