Vulnerability Title
N/A
Vulnerability 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.

PulseAudio 多个拒绝服务漏洞
Vulnerability Description
PulseAudio允许远程攻击者借助(1)发送到TCP端口9875的FRAME_SIZE_MAX_ALLOW的PA_PSTREAM_DESCRIPTOR_LENGTH值(2)发送到TCP端口9875为0的PA_PSTREAM_DESCRIPTOR_LENGTH值从而引发了pa_memblock_new长度判断失败，引起拒绝服务攻击(后台程序崩溃)。并且远程验证用户通过(3)发送到UDP端口9875的空数据包触发pa_sdp_parse判断失败(4)发送到TCP端口9875的构造的数据包触发pa_memb
