Title: PeerCast: Buffer overflow (GLSA 200801-22)
Severity: high
Exploitable: remote
Date: January 30, 2008
Bug(s): #202747
ID: 200801-22

Synopsis

A buffer overflow vulnerability has been discovered in PeerCast.

Background

PeerCast is a client and server for P2P-radio network

Affected Packages

Package: media-sound/peercast
Vulnerable: < 0.1218
Unaffected: >= 0.1218
Architectures: All supported architectures


Description

Luigi Auriemma reported a heap-based buffer overflow within the "handshakeHTTP()" function when processing HTTP requests.

Impact

A remote attacker could send a specially crafted request to the vulnerable server, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the PeerCast server, usually "nobody".

Workaround

There is no known workaround at this time.

Resolution

All PeerCast users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/peercast-0.1218"
