Description |
35 |
=========== |
36 |
|
37 |
James Bercegay of the GulfTech Security Research Team discovered that |
38 |
PeerCast insecurely implements formatted printing when receiving a |

request with a malformed URL. |

|
41 |
Impact |
42 |
====== |
43 |
|
44 |
A remote attacker could exploit this vulnerability by sending a request |
45 |
with a specially crafted URL to a PeerCast server to execute arbitrary |
46 |
code. |
47 |
|
48 |
Workaround |
49 |
========== |
50 |
|
51 |
There is no known workaround at this time. |
52 |
|
53 |
Resolution |
54 |
========== |
55 |
|
56 |
All PeerCast users should upgrade to the latest available version: |
57 |
|
58 |
# emerge --sync |
59 |
# emerge --ask --oneshot --verbose ">=media-sound/peercast-0.1212" |
