Severity: high
Exploitable: remote
Date: March 21, 2006
Bug(s): #123432
ID: 200603-17

Synopsis

PeerCast is vulnerable to a buffer overflow that may lead to the execution of arbitrary code.

Background

PeerCast is a Peer to Peer broadcasting technology for listening to radio and watching video on the Internet.

Affected Packages

Description

INFIGO discovered a problem in the URL handling code. Buffers that are allocated on the stack can be overflowed inside of nextCGIarg() function.

Impact

By sending a specially crafted request to the HTTP server, a remote attacker can cause a stack overflow, resulting in the execution of arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/peercast-0.1217"
