Bug ID: 92568
Summary: [module-rtp-recv] non null terminated string / non
portable sscanf
Product: PulseAudio
Version: unspecified
Hardware: All
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: modules

patch against pa5.0
In rtp.c:
if (sscanf(t+9, "%i %64c", &_payload, c) == 2)
the string c seems to be non-null terminated. It is later used as following:
c[strcspn(c, "\n")] = 0;
The same piece of code is responsible for the inability of pulseaudio on
OpenWRT to handle RTP stream at the rate 48000 from another machine:
[pulseaudio] sdp.c: Failed to parse SDP data: missing data.
It turns out that uClibc does not agree with glibc about "%64c", see
http://git.uclibc.org/uClibc/tree/docs/Glibc_vs_uClibc_Differences.txt
Attached is a patch that should take care of both issues.
